It's 200MSP, not 240MSP, as part of the 50% Sale on Microsoft Studios games, the same price as Dig-Dug but it's still a pretty meh game. It's more like they put time into the glorious water physics than the rest of the game itself. Technically it's a great game, like technically Rage was a great game, that doesn't mean they were games worth playing, imo.
Also I think there's a couple of dozen threads which already mention this and many more games are on sale, such as the DotW thread.
and I'll post wherever I like.
