Fenixp: Do watch a playtrough video / force yourself towards the end. Why would you do that? Well, because the second game fixes vast majority of things you seem to dislike about the fist one - including killing monsters to research them (altho you can still use books if you wish to do that, nice touch I feel.) It also has way higher production values and story seemed, at least to me, far better.
This assumes that I am in fact able to play the second game; I am not. My computer barely surpasses the minimum system requirements for the first game, and even on the lowest graphical setting, I still experience slowdown on occasion, and it flat out failed a CYRI query for the second game. Furthermore, if a game is not fun, the sequel being good is at best an argument for skipping game one and watching its let's play as opposed to actually playing through the first one, as the promise of a marvelous follow up does not make the preceding slog any easier (if anything, it makes it seem to drag even more).
That said, I am considering playing this again after doing some research on the game; it turns out the the game has next to nothing useful to buy, as the best armor can be acquired on a quest (with maybe 1 or set available for sale before then), replacement weapons for my witcher blades are incompatible with/not influenced by the witcher fighting styles (as far as I can tell, the wiki is kind of vague on this) and as a result do not seem to be worth the money. In essence, it seems that all that gold is really useful for, aside from advancing the plot, is for buying alcohol and books, meaning that there is no reason to hoard money, meaning I can proceed through the game more easily without having to agnoize over my finances.
On the other hand, I find it somewhat frustrating that so little in the way of character building is available in terms of equipment; this is usually a key part of most CRPGs in my experience, and without it, all that is left is the largely pre-defined character abilities Geralt acquires throughout the game, making the character feel somewhat static.
