Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
