How do I deploy my project cross platform?

Well I didn’t say anything about any of those things. This exchange started when you stated that the Oracle deployment only works for the platform its run on, which is not true for the SDK deployment despite the fact that it does use Oracles deployment method.

As for your installer system, if its based on ANT it can be easily used by SDK users if they wish to do so. I still see most commercial game projects go the way of Steam though, in which case it won’t give any additional benefit whatsoever.
