Probably a better overall recommendation based on OPs desire for something newer. I can’t say I’ve played it though so can’t personally recommend.
Also, Anomaly definitely runs better on average hardware, and modded Anomaly can look absolutely outstanding.
Might sound weird but maybe STALKER. They’re both older, very charming but very janky open world RPGs, and both have immense modding scenes that have created an experience greater than the sum of its parts.
I was gonna say Morrowind lol
Everybody donate to Pine64 so they can get that open source printer off the ground someday.
GAMMA, HACR, or Anomaly Custom are examples of a few modpacks you should look into. All of them have totally overhauled gunplay and AI afaik
