The download size of TSW2 was just 14.6 GB. However when I looked at the properties after it had installed, it said 49.27 GB ! I presume this was for my preserved collection ( East Coastway and Peninsula Corridor ) - 35GB ? If this is the size of just two routes, what will happen when other preserved routes are added ? not including any new routes I wish to purchase. I will soon run out of disc space ...... haven't seen or heard anything about extra disc space required, have watched most of the streams leading up to the launch, it was stated that the download was 14.6 GB, 20GB on the Steam store page, but said nothing about extra space required for preserved routes. Is it possible to have just the TSW2 base game, to play the new routes and use the new tools without the preserved collection ? or can I uninstall preserved routes from TSW2020 ? Can't remove all of TSW2020 because I will lose the NEC route :-( This issue will probably affect other TSW2 players too. Had I known that it would use up a massive amount of my HDD, I would not have pre-ordered it.
