I started playing mmo's at Vanilla WoW, so I'm familiar with their evolution from that point to what they are today. But honestly, I have no clue how mmo's played before WoW. Everquest, Ultima, Asheron's Call... they're supposed to be the big original three.
Could you guys who played explain how they (or other pre-WoW mmos) were different from Vanilla WoW? Or honestly just describe what was typically involved in playing them. Were quests similar, did they have dungeons and bosses, were the dungeons instanced, did they have raids? Did the classes have talent trees or stuff like that? Was the holy trinity (tank, dps, healer) around since the very beginning? Were they extremely difficult, extremely grindy? I'm just wondering what their gameplay was like.
