The competition tries to simulate the work environment of say a classic small game studio. Most people entering are looking to get a job in the industry eventually.
Think of the end demo as a resumee. Saying i outsourced such and such isnt what you want to do on a resumee, unless your looking for managerial experience. Dare has a stake in your game if your looking at it from the standpoint of making a game to sell after the competition..
Plus there are prizes for best artist, best programmer etc.. outsourcing would make this a fuzzy area..
As they state on the Dare site, it’s not about competing with big companies and making the next Quake etc.. its about showing how you can utilise your versatility as a small company.. typically most games from Dare are quirky.. and unique..
