To save space disk... I can uninstall TSW2020 if I have TSW2 with all the old routes on the same computer? Thanks for your responses.
If you bought it on Steam, it will remain in your library, even if you remove it from your hard drive.
Yes, thanks. Obviously it doesn't make sense for it to remain taking up space when TSW2 has more features than its predecessor. Thank you both for your opinion.
the only real advantage to keeping TSW 2020 is NEC New York, so if you want that, uninstall everything else
