I have the LG VX8000 which is a higher end phone. (I also have Verizon). I have downloaded many games with the hopes of something there to satisfy me on long trips or something. I currently have Atari Legends Vol. 1, Lemmings, Bubble Bobble, Defender, and Prince of Persia.
Atari Legends just plain SUX!!!! I even called and tried to get my money back and they would not allow it. (it has asteroids, Centipede, and Atari Combat (2600 version). all are horible and terribly slow.

Defender is only good for making that cool defender sound at the begining of the game. But as a game it is near impossible to play. There is no control and defender is a hard game to start with.

Bubble Bobble is a little better but still somewhat hard to do on a phone. Plus on this game they put an arcade cabinet graphic on the edges of the screen which make the game screen really small. Hard to see.

Lemmings is fun but a bit hard to control. Not having a mouse makes the curser movement slow. You are allowed to pause, so this helps with the fumbling with the phone trying to get the curser to go.

Prince of persia was the best of the bunch. the game play is somewhat smooth but jerky in parts and the combat gets a little clunky. But this one had the best sound animation and graphics.

Sorry, not a real positive review. Just trying to save you some money and sadness.
Did you have the ngage with Verizon? How was the ngage?
