I have played both BG1 and 2 within the last two years and I still love it. To me it's not just nostalgia. Yes it's old and outdated, but it still has the "magic". The soundtrack alone is just so good.
Then truly you may not like Bg3. WoTR may be the better game for you if you have not played that yet you should check it out.
I'd send you a link to their forums but I get half a dozen warnings not to go near them because the connection is not secured.
