i used to play Draw Something a lot! 'cos so many of my friends were playing. But I got sick of it after awhile. Then it was Scramble With Friends.
But currently I'm in love with RPGs on Android! Especially those by Com2uS and Gamevil. Like Elphis Adventure, Inotia 3, Advena, and Zenonia 4. Downloaded a lot of them although I'm slowly working my way through one by one (haven't got a lot of time to play recently)
