Also finished Zone of Enders for PS2 (which I wanted to play for about 10 years ago, right after I finished Zone of Enders: The Fist of Mars). It was way different than what I expected (I should blame The Fist of Mars for that) but it still was pretty enjoyable despite its flaws. The gameplay is quite good and I really appreciated the lock-on feature since aiming with a joystick is a massive pain in the ass and going up and down by pressing triangle or X can get a bit grating.
What I liked the most about the game is the upgrade system, I found it pretty original. Instead of buying upgrades like in most games you have to look for the driver of said upgrade during each mission (as in, a software driver) and find the suitable server to install it (the non-plot relevant ones are always found in the same map).
My biggest pet peeve was with the main protagonist being a kid. I know I should expect him to be a bit naïve and behave like a kid who got thrown into a life or death situation but man, he sure tries hard to be the most annoying mecha pilot in existence (at least he got in the robot). The worst part is how he doesn’t change one bit through the game. He even got bit in the ass for sparing the final boss’ life, and what did he do after said boss nearly killed his friend and love interest? he beated them and tried to save their life AGAIN flips table
Emulating the game was a bit problematic. Depending on your setup You’d either play it fine with enhanced graphics and stable FPS but without the world map (which is not necessary most of the time, but in some missions it can save you from looking around aimlessly) or having normal graphics and a visible map but some nasty FPS drops from time to time.
On another note, rummaging around in the PS2 catalog I found a game about catfighting (yes, I’m serious) and is as terribad as one would expect xD
