Rogue trader for sure. Honestly, if anyone here hasnt played pathfinder wotr i highly recommend it. It's definitely more advanced and complex than bg3 in terms of ruleset imo but it's really good. Far better mechanically, better quality of life and ui as well by a longshot.
When I first started playing TTRPGs I played some Pathfinder. It's such a good system. It's better than Dnd 5E in my opinion. It's hard to get people to play it though because 5E is so much more approachable. Pathfinder really let's you go crazy with it and do whatever you want.
I haven't played the CRPG though. I'll have to give it a try. I heard about it years ago and then it just disappeared.
