Yeah, the spinning is easier.
With Motion+ it's alot easier to read the wrist-twist.
Bowling has gotten alot easier for me, I dunno if it's because of Motion+ or they tuned it up more or what, but I like it.
I bowled a 201! The highest I bowled on Wii Sports was like a 95.
If only the game had Wi-Fi multiplayer...
To mime: If you liked Wii Sports, yeah, you should buy it.
It's got some great new games, some not so great, but overall it's pretty good.
But if you weren't that into the first one...I'd say rent it.
