Yes! No idea why both failed before, but the rep sent me some new download links and everything was fine... Modern Combat 2 is fairly amazing, seems both smoother and more detailed than N.O.V.A. for sure. Asphalt 6 looks cool, but I need more practice before I really understand how to play it. Gameloft certainly has a few excellent games for the Echo.
If anyone has issues with smoothness, restart the phone and check your running applications. I can get over 250MB free just by turning off Telenav and Maps, games never chug or go haywire. But one warning, several games take up more than 300MB on your SD card. Big maps, full sound and a little video though. Seems worthwhile.
