Aside from gaming there is also another major point to consider. The battery life of the xperia play is unrivaled compared to other android phones. You can easily get through a day without putting it on charge and have some juice left over for the next day. There is no way that the galaxy s2 could hope to compare with that. So for a heavy smartphone user, especially games, the xperia play is the hands down choice. This being my first smartphone I thought getting two days off the charger with average use was normal, but the average phone now needs charged every 7 hours or so and getting through a day is almost unheard of for phones like the thunderbolt and more than likely the galaxy s2.
