i have to agree, a stub on the xcom article is enough, an entire article is unwarranted, especially when the main focus of the article is not actually openxcom.
I think an entire article might be warranted, depending on what you put there (things like the developers, some history about the project, differences between OXC and the vanilla, etc.)
But with more than half of the article being about Piratez, the current page would make more sense to be about it instead of OXC
