I'm totally in for turn based combat !! I beieve, and have full confidence in Larian Studios, turn based combat is a great decision they maked to make D:OS an exellent RPG !
Looking at the video on the D:OS site I'm sure TB combat is also very FUN to play, I'm 100% sure !
I also believe gamers who loves board games like the 999 games (for example The Colonists of Catan) will also love Divinity: Original Sin ! But with the difference D:OS has more : roleplaying & strategy, and so on ... like great soundtracks and Tons of Humour (suggestion, suggestion !!!)
