edit: for those advocating SCS, the man hasn't played the game in 10+ years. He doesn't need that, and plus if he takes our advice of playing vanilla BG1 then he's going to be installing a deprecated and unsupported version of SCS (SCS1 which is no longer maintained).
SCS is an absolute must for BG1 if you want to have any semblance of challenge - otherwise he may drop playthrough after ~4 hours out of boredom, like I did when I replayed it for the first time in also like a decade.
The fact that he hasn't played it for 10 years doesn't make him a retard - let's not treat him as a 12yo who only palyed diablo 3, especially that BG1 SCS is nothing compared to BG2's
