I have bought games from humble store, good store, but they have a rather small selection. I've also seen dyingdreams sale at this forum (
https://bitcointalk.org/index.php?topic=278991.0). And the faulty slow steambits.com. Are there any other reputable sellers?
The game I'm looking for right now is DayZ, so if anyone could help me with that, I'd be very thankful
