I made a page about PS on the dutch wikipedia. I just translated all the info on PS's about page.
The page was deleted within minutes wihtout discussion, the reason: it was an advertisment.
I immediately filled in an appeal. The page was pretty objective, why would it be an advertisment and for example the page about World of Warcraft not be and advertisement. Huh
I guess that's the downside of wikipedia: one moderator in a bad mood and gone is your article.
To get accepted, articles often need a little polish before posting. The best way is to link to as many other articles as possible, for instance to Crystal Space, Atomic Blue, Open-Source in general, acticle "MMORPG" or a list of RPGs in the wikipedia (in your language). Also, don't forget to eventually set a category.
This is the
PS article in the german WP, which definetaly needs an update, but at least it's there. You can take a look at this article and compare what is missing that qualifies it as article and not as ad.
Edit: Also ask this mod for constructive tips in creating that article. Point out that it isn't a commercial project and therefor it's a bit weird to use the word "advertising" in that context, especially as reason to quick-delete an article.
Edit2: The PS article in the german WP had also a difficult past. AFAIK it was also quick-deleted, then restored, then had a deletion-process because of "insignificance" just because of the beta/pre-alpha/whatever status of it. Now its in and will stay
