I wanted to buy Terraria on Steam. Can I then play with a friend who is playing on Xbox?
I don't think so at the moment.
Unfortunately, this is currently not possible.
No.
No you can't. The Steam and console versions currently differ from each other, which makes crossplay impossible. But it may well be that in the (rather distant) future, crossplay will also be possible at some point.
Not in the current situation, which I think is a shame. But who knows, Re-Logic said when they released the last update that there would be no more, but some came anyway. Maybe it will come.
