Elmofongo: Heck I am just playing on the easiet difficulty because I have no idea of this game's rules and systems.
Big mistake, BIG mistake. The combat system itself has no depth whatsoever, what DOES have at least some depth are the signs and the alchemy system and only on hard difficulty is their use really required to get anywhere. The combat isn't polished either way and even performing the exact same maneuvers you may win a fight almost unscathed or get torn to pieces. However, you WILL see your odds improve massively if you take the time to utilise all these other mechanics and systems. I'm not defending the combat system but it is far more bearable if you perceive building combos by clicking at the right time as a base requirement, not the thing that you have to master (just like quick reflexes aren't the key to mastering RTS games but are required to make good strategies work).
I never played the game on easy myself but after my first approach I never even considered to play it on normal difficulty ever again, the only way I can get any joy out of the combat is by playing it on hard and depending on alchemy - well, and my character build (although you can't really go wrong there in TW1).
Elmofongo: So far this game is so clearly suffering from First Game syndrome as in this is clearly CDProjeckt first game they ever made.
Well, I really think the main thing to consider is the context the game was developed and released in. Keep in mind that the game was made during that transition period where RPGs were still evolving from pen and paper adaptations to action games with RPG elements. The Witcher 1 was one of the last titles from that generation of RPGs that tried really hard to look like action games despite being actually powered by stats and random numbers. Keep in mind that TW1 was released just before Mass Effect. Plus they decided to abandon various genre tropes, like loot-centric progression and reward loops, to support a more believable world and narrative and sadly that makes the game lacking in some areas as they clearly didn't have the time and/or resources to make up for the holes these decisions left behind.
Well, and then there's this ethnic thing. TW1 was developed for Polish gamers, a lot of that stuff that feels just weird and amateurish to western players in the first agme was actually perfectly spot on in the Polish version and in my opinion an amazing adaptation of the source material (much more faithful than the seuquels). I guess as a western player one should approach the first Witcher game like foreign cinema. It's weird but for cultural reasons that one should respect.
That said: I got The Witcher almost day 1 and only finished it in 2014. It really IS tiresome and botched in a number of ways...
