Since the vox is primarily an ereader, I don't get the sense that a lot of folks here are interested in games. But I bet there are at least a few lurkers here who might be.
The best game I've found so far is Apparatus. It is android only which makes it all the cooler. It is a physics based puzzle game. I'm not sure but I think it might only be for sale through the Market:

You can get a great deal right now on some other cool games via the Humble Bundle for Android. No market access for this required. This is a sale lasting 11 more days. There are three games: EDGE, Osmos and Anomaly. It's name your price with whatever percentage you designate going to charity. So you can get the 3 games for a penny. However, if you match the average price paid (currently $6.05) you also get World of Goo which is a great game. Additionally, you get the pc/mac/linux versions of the games too if you want. I've tried all four of the games in the bundle on the vox and they all play fine. Here is the cnet article where I found out about the bundle:
