Dragon Age Inquisition Key Invalid
- 10 years ago
Dragon Age Inquisition isn't on Steam, which is why your key will not be accepted. The game is only redeemable on Origin, like pretty much all recent EA games.
More importantly, G2A is a key reseller, and many of the keys they sell are obtained illegally, sometimes by means of credit card fraud. Buying from them is something you do at your own risk. If your key isn't accepted, you have to ask G2A for a refund. In any case, EA is not responsible because G2A are not an approved seller.
You can try redeeming the key on Origin, but since the key may be acquired using illegal means, this could result in an account ban (you should check Origin's terms of use just to be sure). Ubisoft once deactivated a large number of game copies from people's accounts because G2A had acquired the keys using stolen credit cards.
