This is really inspiring! I really like Sokpop and Tiny Mass' style of short, self-contained games done within clear time limit. I think it's helping me combat my own tendency to let scope creep go on and on until the entire project becomes too overwhelming.
On the other hand, I have also found that as I grow up and within what spare time can be squirreled away as working adults...short games are the coolest thing ever! Committing to a 200 hours game is difficult, but I can always find time to play a full run of Within a Dead City...or two.
