I agree on the release speed point, although until my finances got tight in the middle of last year I did pledge to DC. as j4yj4m said though, the pledge was more of a tip for good work done in the past not as a payment for the next update and I think that's how DC has been able to keep a large amount of followers with such a sparse and sporadic release calendar.Okay, I can get behind that to a large extent.
I'm not particularly concerned with the release speed. I still think it could/should be better, but I have never pledged to DC and don't follow him regularly. Summertime Saga is one of those games that are on my list and that I play, but that I only check on once in a while to see if something new has happened.
