Cheat Engine is an extremely capable tool too, has lots of reverse engineering features, including a debugger and pointer searching tools, a blue-pill style hypervizor to modify memory undetectably and a very powerful assembly level patcher. Oh, and it's all open source. Seriously nice stuff.

Thank you for this. That program is so nice I think I might even abandon more traditional tools like OllyDbg, since this seems more targeted towards what I usually do with them, anyway.
