I'm not sure if this is the right place to ask this but is train sim world (the one released in 2018) and the new train sim world 2020 the same game? or did the first one like become the 2020 version? I ask because https://showbox.bio/ I was wondering if I buy a physical copy of train sim world will I get the 2020 version or no
Sort of. If you buy Train Sim World it'll update to Train Sim World 2020 but the routes will stay the same, so no LIRR, NTP or MSB. Additionally you cannot buy DLC for TSW2020 anymore so it's not worth buying anyway.
You'd be better posting questions about TSW in the, err, TSW forum: https://forums.dovetailgames.com/forums/trainsimworld/ This is for forum is for Train Simulator Classic (TSC), a different, older, but much more flexible train simulator than TSW.
