It was a pretty damn good game, I agree. Best campaign in any RTS game, ever. Yeah, sure, SC2 has varied missions but the story and settings are just dull. WC3 had some quality voice acting and a really good story to go with it.
Was pretty young when I started playing it, and I didn't even know what Battle.net was until The Frozen Throne was released. All those customs games, man.
Anyone remembers those SotDRP maps and the likes? I used to have a good time with a bunch of friends and Clan members just making campaigns in SotDRP.
