Plutia's CPU form is meant to be a surprise in Rebirth 3. One of the characters says "You don't want to see her CPU form!" a few times before the game reveals it as part of the story. If you play Plutia with the DLC pack, it kind of ruins the reveal.
The good: Good way to get nice and dizzy. 6 degrees of freedom means your mind had better be able to handle 3-space. Nice variety of enemies and weapons in different flavors. Graphics and sound go very well together. The bad: This game doesn't do 4:3 screen resolutions. Running at 1600x900 on a 1600x1200 screen means the Windows desktop will be peeking out at you the whole time. No multiplayer mode. Other: Don't let the graphics fool you. This is a hardcore game. *Restart the game after messing with the settings menu. Messing with settings and diving straight into the game will sometimes cause crash-to-desktop. The Logitech Extreme 3D Pro has a hat which is almost good for strafing. The game considers the 8 positions of the hat as 8 buttons. It won't consider the hat as two axes for me. It is a good controller for sniping, though. Maybe next bugfix? Random drops mean you occasionally get awesome things... and really weak versions of things, and it's usually a whole bunch of one or the other. The crafting system means all the hulls and recipes aren't immediately available when you start the game. These two put together mean you had better have a lot of time on your hands. The nanocart isn't guaranteed to give you anything useful at the end of the level. Often you'll find the choice isn't "Which of these helps me most?" but "Which of these won't mess up my build?" Occasionally you get to one of those poke-box-lock-doors-fight rooms and clear all the enemies, only to find that you're stuck without any enemies left. Maybe next bugfix? No difficulty slider or explore mode. If you don't have a proper controller (or are just slow and uncoordinated), this game is going to be insane (and insanely frustrating), as compared to simply hard. Tested on: Vista AMD Phenom II GTX 770 Patch 2.2.1.4
