I bought Baldur's gate during a GOG sale, but it never clicked with me (not that I gave it very long).
It's not exactly easy to get to grips with if you barely know anything about the rules, is it? I tried reading the manual (which seemed very well made, but way too complicated at 150-odd pages). They should have made a beginner's guide or something, because I just felt overwhelmed by it all.
I might give it another chance if the reviews are good.
Not really. But it helps if you have the original manuals.
I was gobsmacked the day I realised that certain types of weapons would get bonuses against certain types of enemies. (seriously, buy most of your party a blunt weapon to equip in a quick-weapon slot.and switch to it when you engage the undead in melee to see what I mean).
It's not easy to learn, but the depth is rewarding.
