Development Hell: Mech Warrior Tactics is most definitely this. It's been in development for well over 2 years now. Two end of year promises in both 2012 and 2013 for the game to be out in open beta have come and gone, and the original developers were let go because of that. As of late August of 2014, its still in closed Beta, requiring those interested to either hope they get picked as part of the Beta Key lottery, or pay for a founder package, with little to no word from the current developers on its status.
At the end of August, the entire Tactics website down, with a message to check back in 72 hours for updates, citing that there was a major hardware update. However, at the same time, someone from third development team, Blue Lizard games, posted this response to a question asking what was going on when the maintenance went past the posted time frame. Needless to say, fans finding out that the dev team had been quietly removed 8 months ago, has fueled speculation that the game has been cancelled. Those who bought Founders packages, have begun expressing their outrage at Infinite Games Publishing for hiding this fact.
After 3 weeks of Mechwarrior fans asking questions and beginning to threaten legal and financial actions against IGP, they FINALLY updated the MW Tactics website to.....tell the truth that fans had already found out from Blue Lizard, and to now admit they had no servers to run the game now, and are still looking for a new dev team 10 months after getting rid of Blue Lizard games. Yet they insist the game is somehow still in development and the MW tactics website claiming it will remain down for a "While longer". With Online being handed completely off to Piranha Games Inc, and news and evidence of staff being let go, fired, or jumping ship pointing to the publisher shutting down, the game is now looking like VaporWare.
Dueling Games: With the Starsiege series. Ironic, since the developer for those games were the same for the first Mechwarrior game. Mech 3 was the last game which competed with Starsiege, as later games in the Starsiege universe are fast paced first person shooters with jetpacks - Tribes
Executive Meddling: Despite the Mechwarrior franchise having been plagued with copyright issues since the beggining, this has not stopped Piranha Games - the Mechwarrior Online developers - from trying to kill off their competition. Through "mutualagreementwith the project leads", they killed off Mechwarrior Living Legends development. They have legally threatened the MekTek team, the guys who re-released Mechwarrior 4: Mercenaries for free and who were developing several Mechwarrior/Battletech games - Solaris Arena and Assault Tech 1: Battletech. Rumor is that the developers of Mechwarrior Tactics, the free-to-play game based on BattleTech will try to shut down further development of MegaMek, a free and open-source BattleTech game for the PC.
Also, now the free version of Mechwarrior 4 is no longer available due to "legal issues"
There's developer nicknames for some asset variants. There's the Mr. Bubbles Atlas, Noisy Cricket Sparrowhawk, Warthog Bushwacker, Beatstick Mad Cat MKII, and the Toast And Go Harasser.
The Shiva E in Living Legends is nicknamed the Beat Stick Shiva or Flying Beatstick, since it's basically a flying version of the Mad Cat MKII Beatstick.
The Harasser D (which carries 6 flamethrowers): Flamasser
Vehicles with long, unpronounceable names tend to get renamed. The Huitzilopotchli is usually just called a "Huit", "Huey", or pronounced on voice chat as "Who-it". The Hephaestus is typically just "Heph" or "Hepatitis"
In ''Online, the map Terra Therma is often called "Mordor or Mt.Doom" due to being a barren, volcanic waste land with a large volcano with walk ways inside of it in the middle. Occasionally there are jokes claiming a Light mech is carrying The One Ring, and players insisting it (as in the "Ring Bearer" Light mech entirely) be cast into the fires of Mt. Doom
Mechwise, for Online for easy ID, players often call certain popular meta builds by various nicknames depending on loadout. Mechs mounting dual AC/20s are called "Boommechs" (I.E. on a Jaegermech, it get's called BoomJaegers). Dual Gauss Rifle mechs simarly replace the first half the mech's name with "Gauss" (I.E. a K-2 Catapult mounting dual Gauss becomes a Gausspult.
LRM boats get called "LuRMers".
Mounting three or more Ultra Auto Cannons gets the nickname of a DakkaMech.
Hey, It's That Voice!: George Ledoux, the voice actor for MechWarrior 4: Mercenaries' Solaris Arena announcer, "Duncan Fisher", returned in Living Legends to voice Duncan Fisher again for the Solaris Arena gamemode.
Promoted Fanboy: The original Mechwarrior Living Legends project heads were hired by Crytek to help develop the new CryEngine.
What Could Have Been: Before Mechwarrior 2 saw the release it's early alpha and beta stages were more like the original Mechwarrior game in visuals and also had a couple of clan mechs that didn't see use in the final Mechwarrior 2 release.
What eventually became Mechwarrior Online was supposed to have a single-player campaign, and it looked freakin' awesome.
