As we get older, we find we'd typically prefer a great 10-hour game to a pretty good 20-hour game. The Odd Gentlemen – the devs behind upcoming XBLA puzzle-platformer The Misadventures of P.B. Winterbottom
– have realized that as well and it's part of the reason they think indie devs are focusing on smaller, more easily consumable experiences.
As studio co-founder Matt Korba told Gamasutra
