You're not exactly getting a massively packed game here. This is fundmentially Wii sport for the PS3 and it doesnt try to protend otherwise and its very bare boned.
You get a small selection of games, with 3 levels of championship on each. Each game varies in fun and how well it works.
I personally love the archery, find the balls boring, found the volley ball one doesnt work that well and think the Dualing would work better with two motion controllers. The ping-pong shows how accurate the Move is better then any other game. The frisby one is hard to get used to.
Its a mixed bag to be honest, but it shows the potential for the Move. You will get a few good hours out of this and it will be fun at parties with two people playing.
Its worth it I think, but I wouldnt say it shows what the Move can do 100%. I expect better games will come along. But lots of easy trophies too if thats your thing.
