I'm guessing you were never a fan of the NWN series? The combat in TW was pretty typical for a PC RPG of its time, Difficult Mode + WSAD/Mouse.
EDIT: Those modes are definitely needed.
I had both TW and Origins. While the dialog in TW can be a little dry, Origins can be a tad overly done. Between both, I thought TW had a better overall story/plot. Felt more modern/up to world, and had a more realistic sense of conflict.
The combat is not so great in an easier difficulty setting, not much going on.
I will be preordering Witcher 3 and waiting for DA:I to prove itself(no preorder for you EA, not after the schiit that was the ME3 ending).
Witcher one was harder than 2. Witcher 2 was like ezmode. Geralt does sound a bit monotone in his line delivery, but since I think the rest of the VA was good, I assume it's part of the character(I have yet to read the books).
The menu system is awkward for about 3 minutes. Ass Creed still stands out for me as having the worst user->game iteration of any game I've ever played.
AC3 was more like a movie than a video game, watched my younger brother from beginning to end lol. The menu system was alright I guess on a console, I didn't get very far on the PC (was way more fun watching).
Anyone see FFXV? Square Enix may roll it out on PCs given there is a high interest. Will probably take some effort in re-engineering the interfaces for an optimal PC experience.
