That's precisely why some people find it so hard to make a game quickly. My usual approach is also to do whatever I feel like doing on a game at the time and just chip away until it's eventually done. If I'd done hash that way it would have probably taken 3 weeks rather than 3, 8 hour days. My point is that if you do discipline yourself into getting everything done quickly and in order you would be surprised how little time it takes. A game that took me a month to make could have been condensed down to about a weeks work or less if I pushed myself and ignored those "I will do that bit tomorrow" feelings.

It's not for everyone, but I've finished 4 games this month and I'm well into another larger one. It's just a shame I start uni again next week!
