While I don't strictly agree with the OP I think this is a good point. The game should use a few flat checks. For example the door at Waukeen's Rest if you roll a 20 a 6 strength character can open it, if you roll 1 a 20 strength character can fail at it. I know dice rolling is ultimately pure abstraction but certain things simply aren't chance. If you're strong you can always lift a boulder, jump so far, etc. While being intelligent might not mean you're infallible in your mushroom recall skills.
I think a few flat checks here or there would really help a lot. Also some reliance on simply "saying the right thing" would be nice too. Mostly all the dialogue comes down to rolls and checks but rarely are we as players challenged to know what to say, which can be a little unfortunate.
So you think they should do away with Dungeons and Dragons - as well as the Baldur's Gate IP - so that it works like a completely different game...
