well, playing a game (any game, not just pc, for that matter) is all about having fun. if someone doesn't derive fun from playing bd, then there is no point for him/her to continue playing.
Very true, Crusader <img src="/ubbthreads/images/graemlins/up.gif" alt="" /> - as long as a gamer keeps this in mind and knows which his/her personal preferences are to gain fun (and knows what puts her/him off), I think frustration and disappointment can be moderated.
And here I believe, other opinions can be helpful if the potential gamer wants to buy a game and get informations from those playing it: this gamer says, what she/he likes and wants in a game - the others answer. Demos are only a limited source to get a gripe for a game from my XP. Gee, had I known that unlimited monster respawn was in Sacred, I wouldn't have bought it, in spite of the demo. Maybe I missed this info, though I searched reviews and the forum there. In any case, as I know my preferences very well (NO monster respawn - never!), I don't blame it on the game - maybe I should have researched thoroughly and not bought the game at once. So, I'll keep this in mind and not buy rashly again.
Judgementals are unnecessary then IMO, such as: clumsy interface, graphics are bad etc. Same goes for: "but I want the game to be such and such, I want to have this/that in it" (not meaning code program errors now) - or comparing game A to B, if not meant as a suggestion for the next part.
Again: my opinion is strictly subjective.
