It is the Divinity engine people. This engine cannot and will never be capable of RTWP. Get over it. It is the engine they are using and it is a turn based engine. Please stop suggesting this that the game engine cannot do. This also goes for the 6 man party. This engine cannot do 6 man parties. It is a limitation of the engine and no amount of whinning about it will change it.
This is just silly stuff. There's no such limitations.
