Maybe you didn't see that one right. 300 horses. With people, chatting up a storm, while moving around, plus whatever is being dropped and what they're wearing, plus all the animations for NPC's and area, plus trades. ANY computer would get lag from that. I think it wouldn't be horrible to see NPC merchants with carts with donkeys attached, but it's not realistic for players to have it. Especially the dragon part. Now, I could see someone using an entertainment skill of some sort charming a snake, then working their way up to charming a dragon for some sort of quest where you ahve to get treasure without killing the dragon, but other than that, I see no possibilities.
