Are there any games out there for Chinese people to learn English?

I really want to help some of my Chinese speaking friends learn some English in a fun way but I can't find any games (or websites) to give them a link to. Like, when I study Chinese, I use IPhone apps like Mindsnacks and Writer as well as Byki on the Computer. I also watch videos like "Growing up with Chinese" on youtube. It seems there's so many resources I can use to learn Chinese but there's like none for Chinese people to learn English. Can anyone else find an English learning website/game so I can help my friends? (preferably free or cheap) Thanks!

Forget about it. I used to play dragon oath. But you will find all players always say the similar words and sentences.eg: sisi (jion the team), appoint me the leader, atk, don't use ** skill, wts(want to sell), etc.

when you already play a game, will you payed much attention on every words to study English than leveling up, earning money, make equipment?
Are the words useful in the real life?

I do think it's a slow way learning English.
