Microsoft Flight Simulation is now open for an in-beta beta preemptive experience.

Earlier this week, Microsoft Flight Simulation announced that it would be released on August 18th, and interested people were ready to snap up a huge “installation package” of 10 double-decker DVDs. With the first Tech Alpha beta nearly a year out and internal testing drawing to a close at the end of this month, this week’s update has naturally caught the attention of many fans. Microsoft today unveiled a new in-game market partner program in the form of an SDK update.

Microsoft Flight Simulation is now open for an in-beta beta preemptive experience.

There’s also good news for people who attend Tech Alpha, because they’re given preemptive access to the beta version, and the non-disclosure agreement will still apply.

It is understood that Microsoft will send them invitations starting on July 23, and if all goes well, testers may experience beta testing on July 30, although the nondisclosure agreements established during the Tech Alpha era will still apply.

The announcement of the Market Partner Program means that Microsoft Flight Simulation will have a built-in market place where partners can sell content directly to gamers.

In addition, the company says it will work with more content creators, and while only approved applicants can sell its content on the market, the program’s registration will be completely free.

It’s worth noting that the market will operate in an agency-agent model, meaning that content creators can price each content they submit, and becoming a partner does not change the creator’s ability to sell value-added content on their websites and storefronts.
