I would love to help you out but your question is far too vague. There is no one "great game" that is full of crappy players that you can just go join.
If you are insistent on playing online vs live, then you should be aware that the calibre of player online is MUCH higher at low stakes than it is live.
However, the best advice you can get for playing online, in my opinion, is start to play Pot Limit Omaha. PLO is starting to really explode but it still has lots of new players still learning.
