These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Angst? What Angst?: Purge has had a pretty crappy past as a kid, and you'd think that he'd tell someone about it.
Best Boss Ever: The boss from the fourth mission of the second game is a giant, apish, speaker-handed robot piloted by a mad scientist, and you have to use the power of Space Michael Jackson (voiced by Michael Jackson) to defeat him.
It's Short, so It Sucks : Some complaints...at least until you realize this is actually quite hard! Not to mention, some magazines mentioned that you could beat both games in one afternoon...but didn't complain about the length.
Polished Port: The Steam version of Part 2. Originally falling under Porting Disaster, Sega went out of their way in mid-2014 to fix various dire issues with the game. The launcher no longer has issues saving settings, the entire game can be navigated with a controller, the game shows the correct prompts based on what you choose in the launcher, stability has gotten better, and syncing issues are practically non-existent. It did however remove the Japanese dub, but it was later reinstated along with Japanese FMV's, which the original port lacked. Combine all that together with gorgeous 1080p visuals, and it's by far the definitive version of the game.
A very slight case. The rhythm is slightly "off" in the PS2 version of the game, especially compared to the original Dreamcast game. A skilled player can adjust to it, but it is definitely noticeable enough to cause problems and has been commented on by a number of players.
The first part of the second level in Part One. You have to rescue the space captain and the other staff members; which gets pretty hard when they send some fast commands at you. (Players recommend that, unless your thumb goes fast enough across the D-Pad, you use your two fingers)
For that matter, any level where you have to either get delayed commands ("Up.....up hey!") or where they send a ton of commands at you. (There is one part in stage 4 in Part 2 where you have twenty two commands to repeat!)
Woolseyism: Ulala's name is a localization of Urara (See Meaningful Name), which is a common Japanese name. However, the pronounciation turns it into a pun, since they prounce it as "Ooh-la-la"...which is a phrase that is often uttered by people when they see beautiful women. Conveniently this is part of the game.
