1. Every character in BG2 is a stereotype. Edwin is the arrogant wizard villain. Minsc is the mongoloid fighter with good heart. And so on. Even the voice acting is bad with these horrible accents. In the video you posted I found this marvelous sentence from Minsc “The red wizard risks great harm. Boo is sensitive, and may not just go for the eyes!” Bunch of silly caricatures made for teenagers.
2. If you don’t like BG2 when you are a teenager, you don’t have a heart. If you like BG2 when you are not a teenager, you don’t have a brain.
3. The sad thing is that even when they try to implement serious stuff they are trown all over the place without any logic or relevance.
4. Right at the beginning of Irenicus’ dungeon, you will find a genie making an indirect reference to the prisoner’s dilemma. That is awesome, right! Not really. Whatever answer you choose, you will have to kill things.
5. The random stuff that is supposed to mean something is just a poor excuse to kill things. In fact, the whole game is is just an excuse to kill things. Out, out, linear cRPG! Wrote by an idiot, full of sound and fury, Signifying nothing.
