Pong is pretty cool, but it is hard to really use back/top spin because you can't "feel" it, but the fact that you can do it at all is very nice. Volleyball was hard initially, but it does a few things automatically; all you have to do is aim. Archery is my favorite so far, but my arm gets tired pulling the arrows out of the quiver
Bocce doesn't work great because you can't really utilize spin easily either, but it is interesting. Disc golf is goofy. Does that really exist? Seems kind of lame. The sword fighting game is hard with one controller; I should have ordered 2... It is easy to swing and hard to block
Bowling would have been nice actually. The control feels quite accurate and natural compared to what you would really be doing and there is a LOT of potential here I think.
I tried the Tumble demo too. That one is very cool. Yes, it is sort of just stacking blocks, but it works well and is pretty entertaining. You also have "destruction" mode, where you strategically place mines to bring down a tower and score by how far things go. Control is very precise on this one and graphics are nice looking but simple.
