First game is still good. 2 is mostly an upgrade (a bit more RPG-y, with more varied maps and content). Both give a similar experience though, I would say.
I've played 40 hours or so of 2, and have beaten what I understand as a majority of content. It does kinda run like shit on many PCs. I can run many modern games on at least high/medium 60FPS usually on my older PC, but this one is low/medium and I'm lucky if I get 30 FPS in intense combat situations.
Remnant 1 may be a good call while they polish up and fix performance/gameplay issues with 2.
I still think DOS2 is one of the best games I have ever played, and I played it on release when 80% of the 4th act just broke for me. It gives a ton of freedom, interestingly written characters, and once you get the hang of the combat system it's easy to dominate even with weird builds.
I understand why people aren't it's biggest fans, but giving this one a chance is worth it. Overall, I would say BG3 (played a ton in early access) might be the more accessible game. It's less weird, more cinematic etc. Though, I would expect it to be exceedingly buggy on release so keep that in mind.
