I prefer purely turn-based combat too. However, the system is only part of the equation. Creating interesting, varied encounters is almost as important - and that's why I'd rather replay Icewind Dale or Baldur's Gate than Temple of Elemental Evil. Plus, there are several turn-based goodies being made right now (wasteland 2, chaos chronicles, divinity), so I can deal with a RTwP game.
it has to be done properly, with good pathfinding, zones of control of some kind (what irkes me in infinity games is that you cannot block passages and everyone and his mum can reach mages or archers), ruleset that is made entirely for RTwP and some autopause options.
Arcanum shows us that having both is of no benefit, it just makes each of them much, much worse.
