This is the long 'chillin in lockdown' version. Btw, how many games have totally different dialogue options for super low intelligent characters, eh? You may not be able to finish the game wish such hero, but hey, it's still fun!
And since the game is so open and doesn't shove player into One And Only Right Way To Play, one can replay the whole game many times with such varied builds and options, even if playing a dumb dumb brute. And those random encounters, easter eggs and extra layer of references added a lot of flavour. Everything is so similar and yet so much improved, the world size, amount of locations and stuff in general, some quality of life improvements as well (ability to tell NPC to move was lifesaver). Yes I know some people prefer the way more bleak and dirty world of Fallout 1, but I have spent far more time in F2. Personally I would also mention Fallout 2. And Jon Irenicus was a superb villain IMHO. Going from mediocre band of adventurers into semi-gods was quite a journey and I remember most (if not every - yes I played it a lot) quests and even dialogues, all the riddles etc. I definitely approve of Sarafan's example of Baldur's Gate 2 - I love both games and I think the wilderness and low level exploration in BG1 are interesting and logical in their own rights, but BG2 was trully amazing experience.
