So far the quests aren't bad, but I do find having to hold onto formulas and blueprints for stuff kind of annoying. In the first game you could read it, then throw it away and be fine, but not here. This is also compounded by the fact that unlike the first game, it doesn't tell you what you have already read. In the first, if you highlighted a formula or book, it'll tell you that you have already read it so to prevent wasted money.
Trying to find a formula for those land mine bombs but dunno where to look, probably can't complete the Nekker quest without it (and seriously, fuck nekkers).
Also, if your strapped for cash, just play the arm wrestling game over and over again lol. It's so terribly easy and you can just milk an opponent endlessly for cash.
