tinyE: I keep quitting that game because of the combat! :P It's a mess and requires waaaaaaaaaaaay too much timing. Skip #1 and play W2, they fixed all of that crap. Or just take amok's advice and play Oblivion or Skyrim.
I hated combat in the second one. Absolutely loathe it. It's run of the mill mindless slashing. The first one is simple but tactical and unique with a touch of finesse - exactly how playing as a Witcher should feel. I'm not a great gamer at all, but never for a second had I a problem with combat in the first Witcher and the timing it requires.
GR00T: I don't think any of these are 'beginner-friendly' other than perhaps Driftmoon. The reason I say this is even fairly simple ones like Skyrim rely on things like perks and skills that have synergies and may not be that intuitive to someone new to the genre.
Having said that, my advice to the OP is to just pick a game that seems interesting or appeals to you and then just google search about the rule set the game uses, then jump in and give it a go.
That's actually true, at least that second part. I had absolutely no idea what I was doing when I started Morrowind, and I quite successfully brute-forced my way through it. At least up to a point. I have not actually finished it, so I can't be sure if my character would cut it to the end, but I've played for quite a long time and was fine. In a way not really knowing much and improvising my way through was half the fun.
