is there any difference between republique + deluxe edition upgrade and deluxe edition?
i purchased republique + the upgrade to deluxe edition. so it should be deluxe edition...
but if i view republique deluxe edition, it still says, i don't own it...
should i have purchased repuplique deluxe edition rather than repuplique + uptrade?

It's functionally the same. But the GoG inventory has to list them separately so they can sell each one.
