I used to dabble in Cheat Engine, Tsearch, and IDA Pro, for reversing games. Recently, a nice guy randomly showed me a demo of a modern tool called radare[1]. I was floored by the IDA-like flow-diagrams that it spit out in the terminal[2], and the short commands for navigating/bookmarking/documenting. Nice to see hobbyists don't need to buy IDA anymore!
