I love this game.
I played the PS3 demo last year and bought the full version straight away. This is pretty much a straight port. Theres very little difference in the single and multi player modes. This is a good thing since the PS3 version rocked.
Ive only played it for a few hours yesterday but the multiplayer worked well. I didnt experience any lag or problems.
The idea of the game is pretty simple. You are trying to save or protect your princess while trying to capture the enemys princess. You can stop the enemy from taking back their princess by feeding her cake to fatten her up making it difficult for the enemy team to carry her away. Thats the main game mode but there are alot of other different modes available too.
There are alot of different classes of fighters to choose from too and its easy to swap between them in the middle of a match. You can try and play tactically and harvest resources to strengthen your team or just run in and fight. the single player is great but the multiplayer is the best aspect.
If you have a PS3 I would probably suggest you buy it for the PS3 for bigger online matches and trophy support but this is still an excellent version and its fun to play while out and about.
