How viable is the idea of having a GA Wiki full of Pro-Tips? Edit
I dunno...on one hand it's a good idea, but on the other I don't want to give too much advice and give away all of our tricks...
I say it is up to Vampofval the admin of this page. the ideas of wiki is to provide like a database or info of a specific title, theme, etc. how detailled it will be, depends on the admins (this wiki) objectives.
i believe a simple FAQ will be nice with like questions and simple answers and links to pages with MORE INFO, or what could be more like my interest is in each page add a SUGGESTION or PRO-TIPS as you suggests, it is true it could left you vulnerable or you loss your advantage when people know it, but may make more people interest in play and stay too.
