My first game and I'm still playing it when friends come home.
The game is well-balanced because there's no fighter that is "stronger" or better than another one, you can beat akuma using guille or raiden, just an example.
There's great characters from both organization, yet important characters like Ralf and Leona (from SNK) are missing.
The voice acting of the menu is amazing and it really gives you the feeling that you are participating in a tournament.
The gameplay is perfect, make a team up to 3 players is amazing, you can do great combinations from both SNK and Capcom.
The Final Bosses are very hard to beat even when you beat the other enemies easily, which can make you feel frustrated but if you are perseverant you will feel a great satisfaction after you achieved victory.
If you like 2D figthing games this is a great choice, it's not as good as Marvel vs Capcom but is definitely worth 10 bucks or even 20.
