readig posts on the forums and people saying it has lot s of better routes esp US be a thought suggestion. If TSC could be ported for consoles at least the 9th gen onews
They couldn't happen. It was built for pc and only for pc. Bringing it to consoles requires rebuilding all the hundreds of dlc which at this point is extremely unrealistic
More complicated answer is that all of these big sim games (TS Classic, FSX, DCS, OMSI, etc.) were built in an era where consoles didn't have very good long-term support (especially limited forward compatibility) so the devs just didn't bother making the investment. Nowadays, the core can't be touched a whole lot because of the thousands of mods that would get broken by doing so.
I do not see a reason for this. A big part of any simulator is 3rd party stuff and mods. My installation is 800 GiB. Why would you want to play complex simulators on a console anyway, using awkward button combos, just plug your PC to your TV set.
