Cavalary: Plus that the tablets mean that plenty of the character development is fixed, and even what you can customize needs to be done while following a guide, to keep track of the fixed bonuses and not waste LP.
I don't remember the details of how things worked exactly in G2 but yeah, I remember that the progression was another thing I didn't like in G2. Back in the day all my friends were brutally min-maxing the game, optimizing at every step to achieve the maximum amount of STR or DEX, it's practically all they talked about in the context of G2 while with G1 all we really talked about was the world. And from what I recall feeling like I'm constantly making mistakes in the progression was another thing that kept me from fully enjoying it. It's something I never had with G1, even when I did waste points on useless stuff and did multiclassing.
Cavalary: In terms of mood and style between G2 and G1 though, G2 always struck me as both more and better, the atmosphere, the game world itself, how "real" and lived in it feels, even more so compared to other games of the period.
Ironically that's exactly the area where I personally feel that G1 did a much better job than G2. The colony in G1 was a very coherent and believable place to me. It was not only an interesting and (seemingly) plausible thought-experiment, it also worked perfectly with the scale and concept of the game world. To this day the original Gothic may be the most perfect open RPG world for me in this regard. Going bigger inevitably made G2 more abstract - with their scale and architecture Khorinis and its surroundings felt more like an abstract representation of a medieval city and landscape than an actual place and thus they sacrificed something that was one G1's biggest strengths in my opinion.
I realize that those are sentiments that most players do not share but yeah, I think that's my single biggest problem with G2 compared to G1. Well, that and the fact that to me the true Gothic experience is a brutal dirty world where the sky is never blue - something that G2 also changed. But oh well, to each their own. And I suppose it is good that they did not make the exact same game twice.
