I spent another hour or so with it last night. I am slowly coming around but it is still a little lack luster. At least I have decided to keep it instead of putting it up for sale (which had crossed my mind) Yes you have to re-calibrate every game but it's not too bad, takes about 10 seconds. I am surprised they have sold out at Gamestop, Target had a good 30+ units in stock when I bought mine but that was the same story when I bought my DS on launch day so maybe I just know of a good spot to get stuff
Here is my game by game breakdown..
Archery - This one is a winner. Very fun and has that "pressure's on" feeling while playing the computer. I would probably buy an entire archery game if they make one.
Bocciball - I found this one dull. I might need to get a second controller to enjoy it a little more but playing the computer is a snoozefest.
Table Tennis - Not in to this at all, controls feel shitty.
Volleyball - like slightly better than table tennis, has good responsive controls but just not in to it. Just nothing special about it, feels kind of like a chore to play.
Gladiator Duel - This could have been awesome. It is pretty good as is but the controls feel a little clunky and slow at times. I guess that would be accurate since real gladiator weapons have to be pretty akward but I don't want accurate, I want awesome. The more I play it and the farther I get the game just starts to get frusterating with the hit and miss controls. I hope they make a similar game to this with polished controls and make it a full release, that would be cool.
Overall I think I just set my expectations a little high. Had I never played the Wii I probably would have been a little more impressed but as it sits right now, I am still on the fence. What I am counting on for the PS3 is more grown-up games, I know the Wii has those too but I think the PS3 would be able to do them better. Hopefully they continue in that direction and don't just pump out a ton of mini/party-games and bowling games.
