I copied over my apk (TB restore) of Assassins Creed as well as MC3 (MC3 i had to redownload as I believe they actually download different apk depending on which device you have). THey both work wonderfully (although at first it was getting screwy and i had to clear data and cache including the stuff in the sdcard and redownload all the files). Not sure if i *had* to, but just to be safe, I did it anyways.
Anyways, it scales to full screen, although im thoroughly unimpressed by the graphics, and it shows even more on a 720p screen (that is; how unimpressive the graphics is). But I suppose it'll be a ffew months before games that look amazing in 720p will come out.
