So, I got TSW3 in the sale. First impressions, after completeing the intro part: -Keyboard controls are 99% the same as TSC - big plus! -Graphics quality top notch -Very fluent on a computer that pretty much matches the recommended specs (RTX 3070, 16gigs RAM, 11th gen i7, SSD). -The ability to walk around your train, walk into the cockpit etc is possibly fun for some, but it seems like a novelty gimmick that's gonna get old fast... -Trains seem to have a pretty unrealistic acceleration, I only tried the 66, but 25 km/h within a short time in notch 1 in a 66, OK, it was running lose, but still.... -The track layout at the training centre kinda looks familiar.... ;-)
Wait until you go through scenarios where you're asked to change ends. Also, one of the best things in TSW is the ability to walk around a station, sit into a loco and take over a service, then maybe continue on foot and jump into another train. The only thing that would make this better would be having DLCs connect to each other, so if you drive a train from Riesa to Dresden (DRA) then you could jump into a train to Chemnitz (DCZ), if you own both DLCs.
