I think there's a lot of closed minds here.
I think a PoE style MMORPG would have been great.
I've played BG, BG2, IWD, IWD2, NWN, NWN2, expansions, etc. You know why I liked those games more than their rivals? The Multiplayer. Yes, planescape torment was a great title. But a single player experience will never, ever, ever grant the same satisfaction as a multiplayer one. You can't script anything as funny, dramatic, intense, enraging or emotional as a multiplayer experience.
Those near death fights, the times you aggro a city with a bad pick pocket, pissing off a key NPC and losing out on a quest chain. These moments are all better with friends to experience them with.
Their single player stories were fun, I enjoyed them all. But the multiplayer is what made the game for me. When I saw all of these titles mentioned I'd assumed multiplayer. I was wrong, and while still excited for the game, I can't express my disappointment that my friends and my experience of it will be nothing more than exchanged stories rather than shared ones.
It's not too bad, most of us are having a blast playing Divinity at the minute. It's nailed what we were looking for pretty perfectly. It's a shame it's just 2 players max.
As for an Isometric MMO?
I've always had this idea for a game a bit like Diablo. You roll a character, can take your Char Sheet to different games, progress through the chapters you unlocked. With new chapters / stories to play through at regular content updates. It's my dream game, but it'll probably never happen.
