i diddnt like spider-man, the boss fights were all annoying, and the normal gameplay was a little boring.
Let's golf is a pretty fun golf game, and i personally think the 3d effect is great and really adds to the feel of the game. the only issue is that you will get almost no challenge from the computer unless you play blindfolded, and even they you'll be competitive.
GT Racing seems like a good racing sim for a phone, but it crams way too many controls on to such a tiny screen. It does give a lot of options though... you can use on screen controls to steer and keep the 3d, or you can turn off 3d and use tilt controls.
assassin's creed is ok, i never played it on the 3vo so i don't know how the 3d is on it. i had it on my old epic. This one more than any of the others is really a "phone game". the others do an ok job of mimicking their console big brothers, but this one doesn't seem like it even tries. Still, the gameplay is entertaining enough if you can get it on a sale.
Nova is a solid shooter. The 3d effects is just ok, the gameplay is pretty good and gives you the option to play online (have to be connected to wifi). If you like shooters its the best thing you're gonna fine on the 3vo.
on a side note, Pro Evolution Soccer 2011 on the android market is a blast. It dosnt have 3d but the gameplay is good enough to mention it. Very full featured game.
