Multiwinia is probably best defined by those small moments of joy and horror which, though projected by the player, definitely help make the game interesting. More interesting than most of the rubbish on XBLA.
Though not a casual game by definition, Multiwinia is definitely a game which lends itself to the casual gameplay style. A Domination game will fill an hour here, a co-op match will take up 20 minutes there. Immediately accessible and consistently enjoyable, Multiwinia looks to be a definite must-have game for fans of quick and easy skirmish strategies.
