Really? When I tried it, it was buggy as hell.
Sure, in the official version, you can't walk around the subway, but there are people in it, and you can look out the window, and it tells you what station is next and all that. Actually pretty chill.
Haven't had much problems with bugs, probably depends which version(s) you've tried. As for the rest, maybe I should look for some videos to see for myself. Is there radio on the official one?
