Well it's only 4 of the 10 games. So it isn't reviewable by any means.
Of those 4, two are bad wii tennis rip offs, the third is just laughably awful, and the 4th is entertaining but hopefully it will have more "levels" before the actual game comes out.
Full impressions are in process still. Stupid work makes it hard to get these out early, but expect them on the site by Saturday at the very latest.
