You couldn't be more wrong. RTwP works (in the present tense, not just the past tense) extremely well in all the IE games as well as the NwN games. It also works fantastically in the Pathfinder games. There is ZERO logic to the claim that if a game's rules come from TB TT, then the videogame adaptation must also be TB. Videogames are fundamentally different from TT games. The TB system in TT games is there out of necessity. Nobody chooses TB in TT games because there is no choice. TB is the ONLY way a TT game can possibly be played. However, there is no such LIMITATION in a videogame. So the limitation of TB in a TT game can be dispensed with when that game is adapted for the computer. It is merely a matter of whether the game's developers are technically capable of pulling it off or not.
You enjoying RTwP has no being on the whether or not it is as good system for adapting a turn-based tabletop rule system to the pc, which it demonstrably is not. It was bad for trying to adapt 2E for the Infinity Engine games, causing melee classes to be relegated to auto-attacking tools, and was somehow even worse for NWN, given what had to be cut to make the rule system fit RTwP. Flanking and backstabbing broken, no counterspell, no held action, no called shot, no grappling, no charging, etc, etc.
Then go and compare the adaptation of 3e for NWN 1/2, to Troika's Temple of Elemental Evil. In spite of it being absolutely broken at launch, that game still stands as the best adaptation of any version of DnD to the pc.
Dragonage Origins works because it's not trying to adapt a tabletop ruleset, the entire combat system is tailored for RTwP.
