Question??

My question is I'm Wondering, I have been learning game hacking for about 3 months now.. ( i Know thats not long at all) I have experience in Ce,Wpe pro, also I'm just getting into Reverse Engineering, Using Ollydbg. I can program with C++ at intermediate level. Now to my question since all my learning i want to try to get into hacking now allot more where would be a good place to start and easy game to start off with. I have done DF and Mechquest with Ce, and Wpe pro so i would be Looking for a more difficult level then that. I hope some one can point me in the right direction. Thanks before hand
