Why one team can create a project during a 2-day hackathon, while it takes a year to finish professionally? (Game, chat app, anything.) Well, large organizations have overhead for communication, management, etc (see v). But also there is a statistical effect - if we get many, many shots - sometimes we get lucky (in most cases - not; think of a typical hackathon project - usually it never gets properly started). So, in short, we see a huge survival bias. ...and it takes time to polish rough edges. For example, game Superhot started as a hackathon demo (with a single scene). It took Kickstarted crowdfunding, and a year of work to turn in into a fully-fledged commercially-viable game. (Personally, I think it is one of the most creative game ideas in the last years, especially for VR. I am happy that I crowdfunded it. :))
