I spent some time playing Galaxy Fight tonight. On the surface, it's a game I really want to like-it's developed by Sunsoft, it has colorful & fun characters (especially the Bonus fighters), pretty good music, and I picked up a loose AES cartridge pretty affordably. In practice though, it's just so mediocre. Not a lot of animation, basic backgrounds, difficult to execute combos, and even on Easy the computer is brutal. I finally had to use the UniBIOS to make myself invincible so I could see the later fighters and the end of the game. I'm not sure if I'll keep this game long term.
I haven't played Waku Waku 7 yet, but it sounds like that game lives up to the expectations I have of a Neo Geo game developed by Sunsoft.
