…just as confirmation of the post I made yesterday, check this thread from Indiegamer forums…!
Surely Cas is a pathologic case 😉 hehe but honestly is very usual to sell maximum 5-6 copies / month for a game. Nothing strange, unless you:
a) have a website with 10.000 daily visitors
b) your game is unique
c) you’re already in business from 3+ years
in this case you should sell more than 5 a month 🙂
