I think we have a confusion between ENGINE and SYSTEM, Swordscythe. As I played D&D for over 20 years, I don't have to 'pretend' anything with regard to it - I know it pretty well, including the way it was deliberately designed to encourage teamwork and group play by making sure no single character class could do everything. That is the SYSTEM that both NWN games use. That is simple fact and easily verifiable, should you care to do so. Trying to make a single character game with a SYSTEM designed for multiple characters is a pretty bad design decision, as I'm sure you will agree.
Witcher and NWN2 use the same ENGINE, not the same SYSTEM.
As for both original NWN and The Witcher - yes, I have the original versions of both and played them straight out of the box. NWN was an appalling mess where Witcher's main problem was with the dreadful load times, as noted.
