Now that i got the game (again) lets review.
Marvel vs Capcom 2 is suppose to be the arcade translation for the PS2. lets say...its an ok translation just wish it had 6 button and not 4 button fight buttons..... with is mass amount of characters to choose from...you can never go wrong. Being able to fight as 3 characters instead of 1 makes a tag team worth while. MvC has the game mechanics from the vs series and keeps the formula for it.
I think the game itself is pretty long due to the extra content on the disk. i think you would have a great time if you like fighters. if not....rent it (if possible) or download it onto an emulator, or purchase the arcade cabinate. whatever it is....just make sure that you can enjoy the game while you can. don't overplay it and don't overuse it (scratches) but all in all its a game for fun and friends.
