Diablo 2 made me forget about any other game for years. It's just that damned good.

Diablo. That was easy enough.

Funny enough, I can't stand WoW, but Diablo II is one of my favorite games.

Damn, this is hard.

Diablo 2, Warcraft 3 and WoW are 3 games I played A LOT. Starcraft takes third place
I'll just coin toss.
...
...
Warcraft it is.

Warcraft / WoW for sure!

I love Warcraft 1-3 (RTS), but I'm not interested in World of Warcraft.

So my vote goes to Other - Warcraft.

Lost Vikings was so wonderful

Starcraft by a long long way.

what the hell is blackthorne?

starcraft = the best game ever created. why? because of the absolutely perfect balance. it's the only game that doesn't have a natural exploit due to an overpowered class/race/unit/ability/etc. to go along with a large cast of choices (it's easy to create a balanced game if there're few choices to go with).

Starcraft / Warcraft shouldn't really be considered a different series, as both are very similar in terms of gameplay concept. But once in space and once in Tolkien land. I voted for SC, even though I spent much more time playing W + WoW. But WoW is a negative in this equation.

Warcraft.... I played a LOT of Warcraft 2 even on my PSone, and Warcraft 3 RoC and FT are still on my every PC or laptop to this day. Hell, I play Frozen Throne at least 3 or 4 times a week
