These games must be purchased from the company's website because they're not available in Android Market. So you can't get the Market's fantastic 24-hour refund policy (boo!), but you can browse, purchase, and download the games directly on your HTC EVO 4G (yay!).
Visiting gameloft.com from your EVO will take you to an optimized version of the site that recognizes the phone and lets you pay for games by adding the cost to your monthly bill from Sprint.
The 10 games are UNO, N.O.V.A. Near Orbit Vanguard Alliance, Assassin's Creed – Altair's Chronicles, Dungeon Hunter, Asphalt 5, Let's Golf!, Hero of Sparta, Tom Clancy's H.A.W.X., Real Football 2010, and Gangstar: West Coast Hustle. Each one costs $4.99.
I have a couple of the games and the graphics look amazing on the EVO's large display. The controls are well thought out and gameplay is really smooth as well.
