Batman Returns for Genesis (Sega MegaDrive) is a good game, but a the fighting part is a bit too hard.
I like these old-school games, cuz when I was younger my parents didn't had money to buy me a GEN (MegaDrive) or a SNES, so I could only dream of these cool games at that time. Now that I have my own job, I can afford to get any game I want, for any platform, and I like to play these games even tho some of 'em are really hard... lol
Batman Returns is a good game, at platforming it's ok, but I think the fighting part is a bit too hard. Graphics are nice, but music should be better... (oh well, it's a cartridge, not CD...)
When I was a kid I played, Batman: Return of the Joker, on GameBoy, and this game is similar at gameplay, but a lot more advanced in other terms. If you are an old gamer and like Batman, get this one, you will have some fun, otherwise I recommend: Batman Arkham Asylum (PS3) cuz that game is really Amazing!
