PaterAlf: Possible, 10,000 Desura accounts seems like a very low number to me. But even if the number of accounts is much higher, I doubt that most members ever really bought a game on Desura. And if
Defender's Quest sold only 53 copies there, I'm sure that there are a lot of games, that didn't sell a single copy.
Indeed. There are actually 8,600 people online right now and 989 members joined in the last 24 hours, so a user base of 10,000 is highly unlikely.
Edit: Apparently the record number of people logged into Desura at any one time was 18,815, which blows the 10,000 theory out of the water. I would guess by this around 60,000-70,000 accounts. How many of them are still used is anyone's guess though.
