I know of many games that are already self-contained and portable, so is there any reason why they aren't on the site?
ZSNES is a portable SNES emulater.
Nexuiz is totally portable and its a great game. Open Arena is also portable. There are really a lot of available games that are portable. So, basically, I ask why they aren't on the site.
John's pretty busy at the moment, and he hasn't given others access to the directory, so nothing's in there yet except his apps.
If you want to help, write up a review and information following the same style used in the application directory for every application you'd like to submit, then make a post about it.
