Play one sim, you probably play others. Now they have all kinds from aircraft to boats to trucks to power washing. What other sims are you into? Aside from trains, I like American Truck Simulator and Digital Combat Simulator (aircraft)
I have one of the 5,000 versions of IL-2 but I haven't got around to giving it a deep dive due to my train obsession. ETS2 and ATS also got supplanted by rail vehicles, but I really like them, keep them updated and keep telling myself I need to indulge more, especially now that they've gotten into the parts of the country I'm from. In addition to TSC and TSW, I have Diesel Railcar Simulator, though I had trouble getting into it. Railroader is in a unique status where most nights I try not to play it because if I do there's a danger I'll be switching till sunrise. A category I lament not being able to really indulge in right now is racing sims. While there's far newer available, my heart still belongs to GT Legends.
Main ones I play are Snowrunner (occasionally its Roadcraft spin off). ATS and ETS2, the latter about to get a huge buff with the long awaited Nordic Horizons DLC. Also Farming Sim 25. I have FSX installed but not flown in over a year. MSFS 2020 not currently installed due to the huge HD footprint and just a bit too arcadey. MSFS 2024 above my hardware specs. I have X Plane 11 but not installed, couldn't get my head around the different control commands to the MS products and I disliked the lack of crash detection. Driving, mostly rally games but also have Forza Horizon 4 which I fire up occasionally.
Forgot about Farm Sim. I just have FS 22. Is FS 25 that much different? Diesel Railcar Simulator sits in my Steam least to look at if it goes on sale.
I do like a sim. Ats/ets Flight simulator 2020 Snow runner Roadcraft Construction simulator Airport simulator Airport baggage simulator Fs 25 City skylines if you could class that as a SIM The sims Dakar desert rally Forza F1 There's probably some others I have forgot about and not worth a mention. I'm looking forward to road kings when it releases next year.
I saw my brother playing Airport Sim on XBox. He says it's pretty realistic (aside from a few bugs like clipping issues), not airlines but as logistics on the flight line for the Air Force for 23 years. Almost a little TOO realistic like the long drive out to get the plane and drive it in at 10mph.
Forza and Snow Runner are my two other sims of choice. Occasionally I mess around in MSFS. I used to play Farming Simulator, but I work for a New Holland dealer and there's many times where I try to forget tractors exist outside of work lol.
I still am on FS2020. Is it worth upgrading to FS2024 at considerable cost since this premium title hardly gets discounted and the finer improvements in airborne realism, operations and IFR/navigation elude me? After casually playing FS for a few years I've come to like single prop planes on big tyres under VFR, planes able to land on or take off from any field or bush strip or small GA field. All those jet liners and commercial airports aren't really my fancy. Sightseeing in the rendered world at 3000 ft is fun though.
