Registration for Microsoft's fifth annual Dream Build Play competition opened today. Submissions will be accepted from May 17 through June 14.

Dream Build Play challenges amateur developers to create a game using Microsoft's XNA Game Studio and rewards winners with a cash prize and "the opportunity" for an Xbox Live Arcade publishing contract (though it's a big commitment, previous winner James Silva warns). A total of $75,000 will be up for grabs this year, with $40,000 going to the grand prize winner, $20K to first prize, $10K to second and the remaining $5K to the third prize winner.

Last year's grand prize winner, Lumi (pictured), is available now as an Xbox Live Indie Game. Previous winners include Dust: An Elysian Tale and Silva's The Dishwasher: Dead Samurai. The latter was released on XBLA and its sequel is in the works, while Dust should arrive on XBLA in the near future.

Those wishing to enter this year's competition should head over to the Dream Build Play website.
