I guess my only gripe aside from the dated graphics is even with the big 110 space pack it's really hard to stay out adventuring for too long without going overweight even when breaking down everything and the complete lack of fast travel is going to drive me nuts. With the master trader garb it easily takes 10-15 minutes to get from Cierzo to Berg. If you don't make that set a priority to acquire then it's probably 30+ minutes or longer worth of running/sleeping or popping crap to keep your stamina up which is just tedious once you have done it before and will definitely prevent me from replaying the game after I decide to beat it. Even if it's just a trade cart that I can hire and afk between cities would be a good enough quality of life fix. Difficulty so far hasn't been that bad, but I've been pretty diligent in setting myself up for success via copious amounts of potions/food and what is probably OP gear for the starter zone. I've died twice since I restarted solo and they were both easily avoidable but I didn't respect the NPC damage.
Break down most things into iron scraps - there's a repeatable quest turn in at Vendavel Fortress that is 1 iron = 5s. A lot of weapons you get will sell for more than that, but weight efficiency is a thing to consider. Also, if you have a lot of silver, turn it into gold bars and carry around gold bars mostly instead.
