Yeah, we know you all want Halo on your phones, but some of us like to relive our childhood and play old Atari 2600 games on our phone. (See also 'Decimation X2')
Luckily, we're not alone as JEFBCreating has made Pong7 for our enjoyment. The game has been out for awhile, but it just hit v1.2 with a nice makeover and new features including single player. That's in addition to the already free status (ad supported) and the ability for two-players, which is kind of cool if you have a table and some free time.
The retro graphics are great, the game play smooth and it even has a nice tile. So we have to give it a thumbs up if all you want is some simple Pong action. Pick it up here in the Marketplace.
