For me?
Started with playing the Warcraft 2 Demo on a PC gamer demo disc. I was enamored with Warcraft then and there. My brother managed to actually find the original Warcraft, and we played the hell out of it. He beat it with Orcs, I beat it with Humans(Back when Warcraft Humans were awesome). We then saw Warcraft 2 double pack, bought that, and enjoyed the hell out of that. There was also the old, old, OLD trailer for Diablo 1 (GOOD LUCK). There was also a preview for a game called PAX Imperium but no one knows what the hell happened to that.
Diablo 1 happened, then we learned of Starcraft. The rest writes itself.
