I wouldn't pay 50$ for it but 20$ after patch 1.6 and all is well. If I had more money I'd rather pay 50$ than do whatever rubish rich people do with their money

Maybe I like it because it is somewhat detailed and less metagaming (needing to know what stuff is overpowered with a lot of potential to fudge your character up like oblivion).
I paid big bucks for Witcher and MoTB and 20 bucks for two worlds and its a better game than both those titles. No I don't play games for story and dialogue. If I want that I'll read literature.
This game is loads better than Dungeon Lords (better everything ie artistic direction implentation etc and not just a graphical update to DL). Very different from Fable, Oblivion, and Dungeons and Dragons based games in my opinion.
This game was the first game that let me fulfill my fantasy to make a bow character who used traps who neither sucked (bows in NWN2) or was grade a Cheese (Baldur's Gate spiked traps). I wish the sneak/death attack was a little bit easier to use however.
I'm glad that enemies do not respawn because it mikes shopping more interesting in that you can't just have endless enemies you have to think 'do I really want to buy that'?
Also the medium difficulty is great for me. I have some tough battles. Easy is...well easy. I only died against enemies way harder than me. Thank the heavens that the enemies aren't leveled like in Oblivion (= quagmire of never feeling strong until enemies hit cap). Hard I can beat the first few young grom's (easy goblins) but they are epic battles and I cannot imagine playing that out actually without what I call 'metagaming' (the opposite of immersion..I mean you have to be somewhat concious of things like sword A does more damage than mace B but doesn't hurt skellies etc...but I like to just be like 'bows are cool' 'dirty trick is cool' and not be wrecked because I don't spend in the most effective ****).
