I seem to be the only one that really play these's , but there are some really good games in there that dont cost much and are great time fillers when im unsure what I fancy..
Head shot 2 and Home run challenge are both great hight score attack games.
Emuze and Kodu are great little apps for when im feeling creative.
I check the section every day and download lots of trials to see what they are like , a lot are rubbish but every now and again a really good one comes out ...
