My first game ever was Dune II, yeah very old game, I had 5 years when I first played it. I really loved the game, though I never finished it at that time.
Few years latter my uncle came from Australia to visit my family, and brought some CDs with him. My PC was upgraded during that time, so I could use those CDs; one of the games that were there, was TD. I didn't pay it much attention until I realized that the company who made TD was the same that made Dune II, so I gave it a try, and became addicted to it, then I got Red Alert, and my addiction for the series started (there's a big gap between TD and RA1, called Warcraft II, and another between RA1 and TS called Starcraft

).
I started modding,

because I wanted to cheat, but when I realized that I could do more than cheating, I started to do what we call modding.
BTW, it's funny that I was also introduced into Command and Conquer by my dad, at least in an indirect way, since he was who presented me Dune II.
