HD Games

Looks like Gameloft released "Try & Buy." Kinda awesome since it let's you download a game and try it like a demo before making you pay for the full version. Helps you avoid games you don't like.

Glad they posted a tutorial too:

Try & Buy Android US

I tried a few of these and they are great. I played quite regularly Sparta, and Dungeon Hunter on the Iphone. I will likely buy these ones.
I found the Modern Warfare difficult to control, though that is probably due to my not being used to the controls. after time I am sure it would come easy. the controls were quite well thought out and gave you the real feel of the FPS that you get on a console or PC with independant movement and free-look.

It's too bad you cant transfer license from iPhone to Android, lol.

This iPad exclusive is more Flight Control or Harbor Master than Fieldrunners or Guns N’ Glory, but you won’t hear any complaints from this reviewer. Defend your base by wiping out wave after wave of attackers by drawing a line from your defending aircraft (helicopters and jets) to the oncoming hordes. After attacking, your craft return to base, where you can upgrade their armor or weapons, then send them back out to shock and awe the enemy. The secret sauce? Your base (think of it as a central tower with many turrets atop in the form of your aircraft landing pads) has a crazy-powerful energy field you can trigger when the baddies are about to overrun the ramparts. Everything that touches it explodes instantly. As you work your way through the levels, you’ll unlock fighters that can clear the fog of war to spot tanks in the distance, while others spray groups of mines to litter the playfield. While the levels don’t exactly ramp-up from easy to hard (the toughness of each isn’t apparently until your neck-deep in tanks), you’ll spend many hours working your way through the campaign and endless challenge mode. Worth far more than its dollar menu price.
