To touch on the multiplayer aspect: it used to be standard procedure for PC games to come bundled with the dedicated server so you could host one yourself.

Even with Battlefield games up to I think BFV, we could at least rent servers (meaning that software is out there somewhere) so hosting them ourselves after a studio drops support should be easy. You can still find servers for basically every old Source game if you look hard enough, same with the og Battlefield games, older CoD titles, etc.

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

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.
