Replaying this after 10 or so (if not more) years is quite nostalgic but it does make me realize how much Leo is basically a Shinji clone, complaining all the time but eventually growing up and understanding his purpose in life, it's a pretty simple story but I like it a lot. The FMVs are REALLY low quality considering that it's an early PS2 game but they do add to the charm of the game. Overall it's a pretty short but fast and fun mecha game, and despite some of its ways of reusing content can get annoying, it won't take you out from the experience.
Pretty good soundtrack!
