Be warned: If you are a Pre owner and something you love the most is the games, you will be severely disappointed by both the selection of games on Android and their performance on the Evo.
Between Gameloft, Glu, and EA, there are well over 3 dozen professionally developed 3D games for the Pre (23 of them available from Gameloft alone) I bought most of them. Gameloft releases a new one pretty much every single week. The Pre has a PowerVR GPU which more than compensates for its weaker CPU, and all the games in this category run phenomenally.
Android has only 10 ports of 3D games from Gameloft, and a select handful of other small-time developed (though fairly fun) 3D games. All of the gameloft games were released in a single chunk, and none have been released since then. EA also promised NFS: Shift on June 4th to coincide with the Evo launch. It has gone AWOL with no word from either EA or Sprint. Also, most of these games were originally coded for the OMAP CPU and PowerVR GPU in both the iPhone and Pre, and therefore they run very sloppily on the Evo. This is also because despite the 1ghz CPU, the Evo's GPU is relatively underpowered.
So while in the very near future Android may evolve well enough to support a breadth of high quality games, the Evo itself was obviously not designed with this in mind, (perhaps due to cost-effectiveness ie the 16-bit color screen) and is not ever going to be capable of running games as well as the iPhone or Pre. This is becoming a deal breaker for me and my Evo, and will most likely return it, to wait and see if the Samsung Galaxy S Pro (which apparently has a 1ghz "Hummingbird" CPU and a PowerVR SGX GPU) is as ugly in person as it is in blurry photos.
Edit: Gameloft for some reason has refused to publish their games to the Android Market, save for Asphalt 5. This is most likely due to Googles 24 hour refunds policy. But what this means for you is not only must you purchase the games directly from Gamelofts website or mobile web portal (which only lists 6 of 10 available titles) but you are limited on number of installs, (I exchanged my Evo for a replacement Evo after I bought a Gameloft game so now I am out $5. Waiting on an email response from gameloft...) and I have no idea how updates to those titles would either work since you can't do them through the Market.
