Yes, BG1 and 2 were 2.0; we had no games based on 3.5 and it is unfortunate that there weren't any. Nowhere was it declared that DnD belongs to 3.5 players - it seems like you just have a chip on your shoulder.
I must jump in here and give NWN2 a shoutout (which used 3.5E). The base game was merely decent, but I personally think the expansion (Mask of the Betrayer) is a work of art. One of the best DnD stories to date, and by far my most favorite epic level campaign. You should try it out if you haven't had a chance to play it. The other expansion, Mysteries of Westgate is also worth a play IMO.
Not exactly 3.5, but Pathfinder Kingmaker is based on Pathfinder 1e, which is basically a "modded" version of 3.5e. And it's a fantastic game IMO too.
