Simulators are one of the earliest PC game genres, and remain compelling experiences to this day, even if they're not as popular as they used to be.
I like all kinds of combat flight sims; the MS Combat Flight Simulator from 1998 was something special, and I've had some similar fun in IL-2 Sturmovik. The newest civil air sims are pretty great too, I'll pop on a podcast and make a flight. They're particularly cool in VR.
I've also found the MechWarrior games to be fun, but I've only played 2 and 5. I got to play a bit of Steel Battalion with the full crazy controller at a con a few years back, and that's got to be a lot of fun once you really know what you're doing.
So what's your favorite sim?
Assetto Corsa, hands down. The mod community have made it into something quite special. I've got pretty much every other driving/racing sim as well, but I keep coming back to AC.
Any idea if there is a way to get the mods to work on Linux?
Not sure, maybe through Wine, but I'm almost certain it won't work with my Moza wheel and pedals, or VR.
