I really love the idea of TB-combat. since i have never played TB RPGs (Dragon Age is definitly not turnbased) it adds just a lot of more strategy to the game.
In most ARPGs you just have a winning combo like in D2 if you combined "Way of the Archer" with "Multiple Arrows" you could easily just run through the game an with this i killed Ygerna literally in 10 seconds on nightmare. So in TB-combat i expect a lot more complexity and a lot more Strategy than just a winning combo, no thinking (like in Diablo 3) at all and so on.
If you dont like there is a big choice of games that you can play, but there are not much real TB-RPGs.
