You know what, I don't actually care about the "RPG" rules. I fiddle my nose at them: "fiddle-de-dee!"
(Guess now you know why I decided I had enough of the Codex, huh?
)
Who cares about endless boring rulesets that you need just about a university degree to get completely on top of? I never got to know all the nuances of the various D&D systems, anyway, and I don't care, either.
The main thing to me is that I have fun with a game, and boy, did The Witcher provide me with endless atmospheric hours of fun and enjoyment!
Ok, of course, when you say you're making a 'classic' RPG, and call it one, it should of course still conform to certain RPG rules, but the devs of TW never claimed it was a classic RPG, and as the hybrid that it is, I think it works just fine.
It sure beats NWN2, anyway.
Did any version of it ever crash on any of my rigs? No, not a single one, and I played vanilla Witcher on my now-old rig the moment it was released. Yes, the loading times were a bit slow during my first playthrough, I will admit.
But the loading times of the TWEE on my current rig, is negligible. No worse than Dragon Age or Div 2. So I don't get what the fuss is about.. :shrug:
