What defines an "official key reseller"?For anyone who wants to keep in touch with game sales, I can't recommend enough this subreddit:
https://www.reddit.com/r/GameDeals/
It also has the perk of only allowing official key resellers, so dodgy stuff like G2A won't show up there.
Oh, and before purchasing anything anywhere, it's always worth checking here: https://isthereanydeal.com/ to see if it might not just currently be cheaper somewhere else, and to get an idea of how close the sale is compared to the historical low.
What defines an "official key reseller"?
G2A is a key reseller. Steam, GoG and Epic are not resellers, imo. I understand a reseller sells a key that wasnt directly given to him for sale on their platform. Usually that means pre-owned keys by end users. Steam and co dont sell "used" keys iirc.The game developer determines that. Typically their own store, gog, steam, epic etc. G2A and such sell keys from dubious sources, with no money going to the dev and with the risk of them blocking the key.
For example, I bought il2-Sturmovik BOS, and on the steam forums the Devs explained why they blocked a pile of keys sold on G2A that were stolen from them. Other Devs openly said they prefer you pirating/torrenting it over buying keys from shady resellers.
