After a six year break from gaming thanks to generally being too knackered (small children/young family) I'm getting back on the horse with an Xbox One X for Christmas.
I'm looking at filling in some of the gaps from the past few years with second hand games and see that some people on Trade Me are selling digital download codes rather than physical discs.
How does that work in practice?
Are you allowed to re-sell a digital copy if it's been uninstalled or will the download code be permanently locked to particular account once it has been activated for the first time?
