These are not the only titles available for the game-centric handset, though - the Get Games app pulled a list of 36 more games, which are compatible with the handset's controller. Some of the titles led you to Android Market, others to developers' sites, where you can purchase or download them (a lot are actually free, and the rest are at smartphone app prices). This list is sure to grow with time.
What we immediately noticed is that when you download one of the titles that is not preinstalled, it goes into the Xperia Play app interface, along with the preinstalled titles. The key difference we saw was when we needed to do something on the phone, but were in the middle of a game, and went out with the home key. The games we had from the start stayed paused in the notification bar, so a quick pull after we were done, and we went back where we left off. With a free title we downloaded afterwards, the appearance in the notification bar as an active game was missing, but it paused alright, and we were able to resume where we left off by just tapping on its icon in the Xperia Play app.
The gameplay on all of the 5 titles we tried was quite good, and we only used the touchscreen a few times because we ran these games for the first time, and it was easier than trying out what to press on the gamepad to exit the title. The D-Pad keys and the four PlayStation action buttons have just enough travel to feel easy on the fingers, but not wobbly, and the whole controller construction is very sturdy. In a few games, like FIFA 10, and Star Batallion, the two circular analog pads came into play for various tasks, and the two shoulder buttons are very comfortable and sensitive when the going got tough.
Have a look at the short gameplay we scored on each of the preinstalled games, tells us what you think, and don't judge our lousy effort too harsh if you are a hardcore gamer, we were just testing. Oh, did we mention you can map the buttons on the PlayStation-style controller to play titles from the abundance of console emulators on Android Market? Yes, you can, and with ease, which just expanded your available titles by several hundreds, if not thousands.
