I had a pokémon phase around gen 6/7 including ORAS, and partly to complete dexes I got previous DS games around that time too. Got Pearl/Diamond and Black/White and shared one of each with my sister so we can play in parallel and trade.
I had a blast with black, but pearl... Not so much. It felt like a boring crawl. Mostly because of the terrible pokémon distribution. Seriously, there's a fire-type elite 4 and there are literally not enough fire-types in the game for him to have a complete team, even counting the fire starter! And one game doesn't have any access to dark type until 6th gym or so, while the other has one in a very early area.
And the pokémon that are there feel like they're always the same, in good part because they decided to keep a lot of pokémon exclusively for the post game area.
BG3? Not sure I am seeing the influence here.
If anything Firaxis's take on XCOM has made turn based tactics somewhat mainstream again, and Ubisoft has already tried to surf on this trend once with Mario+Rabbids.
