Microsoft announced today the availabilite at the end of the month of XNA Studio Express. This development suite, costing $100 a year, will allow anyone with a bit of programming knowledge to create his own games for PC and for Xbox 360. The Xbox Live distribution system isn't really well known yet, but I think we can count on Microsoft to really push this content. In the news you'll find images from demos done with XNA Express and/or with the Torque Engine it's shipped with. Update : One small but important information. The development environment itself seems to be free, the $99 a year subscription would only be necessary to be able to use the compiled code on the 360.
