If the games are open source, yes. We do NOT allow you to do anything remotely illegal, such as sharing copyrighted source code which is not rightfully yours to share. If it's illegal, don't do it. If it's legal and within the x10Hosting terms of service, of course you can.
We review accounts by hand all the time, so if you're doing anything illegal you'll get suspended or terminated without warning if it's bad enough.
