and each update provides several hours of playtime
..which they will not. 0.1 offers like 20-30 minutes if you read everything and new at it. Update can't possibly offer much more than that. He had much more time to deliver 0.1 than he had for the making of 0.2.
I don't mind waiting for a good game to update.
If you would be spending 100$ per month perhaps you would
What i'm saying is that its his best interest to stick with 2 months at maximum. Otherwise if the updates will consistently pass 3 billing deadline, people might have the idea of "Hey, if it takes 3 months, why shouldn't i cancel and just pledge every 3 months". As a Dev he should be striving to avoid that by offering something for the monthly contribution. Offering something only for 3 months worth of pledges is not the brightest idea. This is business in the end. Those on the higher tiers simply would reconsider their contribution and would probably move to a lower one if they don't get something for their money. Projects with low rate of updates do work out but with lowtier patrons. If he wants to keep the hightier ones its not enough to simply do a splendid job, you have to do it on time as well. The most successful projects work with almost clockwork precision when it comes to release dates. He set a very high goal for himself so i'd expect him to be tryting hard to achieve that and that includes reasonable release dates that he keeps.
This is still a very new project, its all fine that he is getting the idea what he is able to do in a set amount of time with his new toys and with teamwork but has to set deadline for himself as well. Pledgers are billed with pinpoint accuracy you see.
