To this day, the only two games I have not tried cheats in is Command & Conquer Generals and M&B.
That's what I thought at least... Then I figured I've used 3 text tweaks.. Village elder and guildmaster in menu, all taxes collected from 1 fief. Would you call this cheating?
And, I will probably cheat at one point (With a new char, or on a different save) just to try it out.. pwn like mad.. Fun for an hour or two..
(And the reason why I have not tried cheats in C&C Generals is cause 1: I have not found any, 2: I don't really need any since I pwn the computer and suck against humans.. and you can't cheat against humans...)
Don't feel bad about cheating, just don't brag and say you are a really good player and show of screenshots of 600 damage hits and think people would reply "Damn.. you're good! Can I touch you?"
