Works, plays fine right now? I don't see the problem. The continued recent release of stuff like the Wasteland series, Pathfinder series, Expeditions series, etc shows that the formula still works just fine.
None of those are particularly taking the world by storm. Maybe someday a studio will make a AAA BG-like, but that hasn’t happened since Dragon Age Origins, and since then each title has been moving further away from that model. The new one is apparently going to be a straight action game.
I love Infinity Engine games, but I know if I didn’t grow up with I would never bother putting up with dated mechanics and gameplay designs. Being built around D&D 2nd Edition doesn’t help. For as much as I loved it as a kid, that is a janky, convoluted mess of a rules system.
