Hell yeah!LongAndShort said:Age of Empires II.
I'd owned and played a few games before AoE 2, but it was the first game that really drew me in, kept me invested. Jeez, I must have played the William Wallace and Barbarossa campaigns a dozen times.
I played some NES/SNES and stuff, but AoE2 is the first game I remember obsessing over. Then came Diablo 2 and sealed the deal.
