- Author Appeal: You know you're in an Obsidian game when it features waking up at the morgue, masks, haunted ruins, hunger as an almost elemental force, mentor figures whose teachings were wrong, misguided, or evil, ghosts and zombies, living darkness and an army of invisible assassins, constructs (droids in this case) in a prominent role, not one but two blind seers, a dreaded, nigh-unstoppable warrior fueled by the power of belief, men who refuse to die, past wars, past sins, an unlikely party of lost souls thrust together seemingly by fate, complex moral choices with no easy answers, and extensive dialogue trees which serve to turn the listener's entire worldview on its ear.
- To top it all off, at the end of the game, Kreia uses her visions to give you what is effectively a showreel of all the places you went and the consequences of your actions.
- B-Team Sequel: Created by Obsidian rather than the creators of the first game, Bioware.
- Creator Backlash: Chris Avellone isn't overly proud of the finished game. His main problem being that he feels the game's story came off as being a lot more bitter and heavy-handed than he had really intended it to.
- Christmas Rushed: Actually a Double Subverted example. Originally the game was to be published around Christmas 2004 and have a relatively short development cycle, but mid-way into development LucasArts announced to Obsidian that, due to their impressive results, they were delaying the game's release so they could expand the game's scope. Obsidian took this chance happily, only for LucasArts to suddenly hit a financial rough patch and revert back to a Christmas 2004 release. Unfortunately for Obsidian, the agreement about the delay had been a spoken agreement and not a signed one, leaving them no choice but to comply. A great deal of the game's content was thus cut, unfinished, or riddled with bugs, resulting in a lot of the tropes on this page.
- Cowboy BeBop at His Computer: An article about the game in a Spanish magazine showed an image of Darth Nihilus labeled as "Darth Revan", which caused plenty of confusion. Sumed to the fact that Nihilus appears multiple times in the game without being called by his name and Revan gets mentioned a lot without appearing physically (except a living flashback in Korriban where he shows silent and masked — just like Nihilus), many players in Spain who had not played the first game reached the battle of Telos without fully understanding the background and genuinely believing they were going to face Revan.
- Development Gag: "I'm Atton. I actually wasn't supposed to make it into the final game, but I was created at the last minute. Blame my agent. I was actually slated for a spin-off to Jedi Knight, but I don't want to talk about what happened there."
- Doing It for the Art: In order to prepare for writing the game, Chris Avellone went on a major Archive Binge of the Star Wars Expanded Universe, playing through the entire first game, rewatching every Star Wars movie, reading nearly every Expanded Universe book (!), and even enduring the The Star Wars Holiday Special (!!!) for the sake of fully understanding the universe he was writing. As a result, there are an impressive amount of nods to the Star Wars canon — down to the most minute details — as well as entire plot threads woven from throw-away background material from the first game. It also tears the basic mythological and ethical system of the setting into pieces, but that's par for the course with him.
- Executive Meddling: KotOR II is one of the poster children for this trope. You wondered why the last act felt so rushed and the ending so inconclusive? That's why. Not only did they insist that the game be released by an unrealistic deadline, they even went so far as refusing to let Obsidian release a patch later to restore the missing content!
- God Never Said That: Some of the game's detractors claim that Chris Avellone openly despises Star Wars and its fans and wrote the game as a personal insult. This is hyperbole at best — the most that he's said to that effect is that he "hates" certain aspects of the expanded universe lore. Beyond that, he's gone as far as to say that he loves Star Wars, highly praises the first game, and has admitted that the final product was far more bitter and heavy-handed than he intended it to be.
- Screwed by the Network: Twice even. LucasArts, the publisher, wanted to ensure that the game would be ready for a Christmas release. This led to a unrealistically short development cycle of 13 months, which ultimately left the game incomplete in many respects. Obsidian, the developers, were so annoyed about having to release an incomplete game that they offered to make a mass-content patch which would have restored it to its planned glory. LucasArts, for reasons unfathomable to fans, denied this request. Modders have done their best to compensate, though.
- Shrug of God: When asked about the popular "Kreia is Arren Kae" theory, Chris Avellone simply stated "Can't comment, but good catch. Sorry." He used the phrase in the past when writing the Fallout Bible, where it generally meant "Not intentional, but I like it."
- Troubled Production:
- In many interviews, the production team spoke in length of the many challenges they faced when making the game. Not only it had a very short development cycle and a stubborn publisher, the company was just getting together and didn't even had an office yet. They set up in Feargus Urquhart's attic and when someone turned on the microwave, the fuses will blow up and computers will go down. The team of rookies was small and had to learn how to work with the new Odyssey Engine. With time running out, this led to things getting cut, low music sampling quality and tons of unresolved bugs.
- The planned story was written before Knights of the Old Republic's release and Chris Avellone didn't even had access to the game. When he finally did, he threw his script in the bin.
- What Could Have Been: A massive amount of content was left by the wayside in Obsidian's rush to get the game out for its original scheduled release. Most of the removed content (like the ending) would have been restored by a patch if LucasArts had not prevented them from releasing it. What is known about the planned ending would have been legendary if completed.
- What's even more infuriating was a revelation from Feargus Urquhart. They originally signed for a short development cycle. After hitting a few milestones, LucasArts was pleasantly surprised of the rookie studio's work. So much that they decided to give Obsidian a few months of extension to complete the game! WOOHOO! ...Except Obsidian forgot to amend the contract. After LucasArts experienced some financial difficulties, they changed their minds and said the game will be released earlier as originally planned. D'OH!
- Obsidian also had plans for a sequel that unfortunately never got off the ground.
- Two events occurred in-game that were clearly intended to foreshadow future games or stories: Darth Nihilus' body crumbling away in a Dark Side version of Obi-Wan's "death", and Kreia declaring that there will always be a Darth Traya. The restructuring of the Star Wars Expanded Universe and the MMO sequel's shift of focus to the True Sith plotline seems to have killed both.
- Players were originally supposed to encounter Lonna Vash alive on the cut planet M4-78 where she would've had a padawan who had gone renegade after mistakenly believing that Vash had died. In the end, Vash would've sacrificed herself to buy the Exile time to escape Darth Sion. Some dialogue for this was recorded, but then M4-78 ended up getting cut and replaced with Korriban. With no time to implement anything new for her (and too late to simply cut her entirely), they just had her killed off-screen by Sion on Korriban.
- Hanharr was originally planned to be trainable as a Dark Jedi like other party members, but an edict from George Lucas at the time banned force-sensitive wookies.
- As part of Bioware's original concept for KOTOR2, they planned on giving the PC a master of the same species as Yoda — but secretly treacherous and evil.
