Icewind Dale I was better than II in every way, because it was much more true roleplaying. The characters were nice, and the dialoges were much better too. Neverwinter Nights ís a true RPG, but I found it very blocky, unconvincing and lacking every detail. Look at the graphics of something in your inventory for example, it is horrible.
As for the graphics of BGII.. I really like them, only the models aren't very good. Well, graphics don't matter much for me.
And Janggut, I do like Dungeon Siege II for example. It is a nice game, with detail. However, it is not a RPG, and thus it is not really my type of game. Because you dont feel as if you are the character.
And thanks for the replies. Also, is my english acceptable? I am from the Netherlands, and I am not very old myself, though I play RPG's since I was 5 years old. (Baldur's Gate, and well, I didn't understand everything, but I loved it)
