Say what you will about the other wiki, but it had a pretty damn good layout in terms of how the information was organized.
Currently, this wiki seems to be organized by 'brand' - Nintendo, Sony, Microsoft, etc. etc. While there's nothing inherently wrong with that, I felt that the other layout - e.g., by console - was significantly more intuitive and useful in general.
That being said, here's a brief overview of what I think this wiki should have and how it should be organized:
-Pages organized by system, rather than company brand
-Include all types of library titles (including PSN and XBLA games)
-Allow some sort of feedback in regards to whether a game should be in the list or not
-Include the original imagepasta and consider updating them
-Include some sort of 'review' section, separate from the system pages
-A page for MMOs
-A page for emulators (consider adding this on the system page?)
-A page for recommended Let's Players* (*Casual shit?)
-A link to the huge Vidya Soundtrack collection, including the 'albums'
-A collection of '/v/ game proposals', i.e. PRESSURE, Airlock, etc. etc.
-Consider scraping the AVGD threads for projects currently being worked on
-Specialized categories? (Roguelikes, H-games, SHMUPS, Horror, etc. etc.? Separate from system pages?)
I'd love to hear what other /v/irgins have to say about it, because the other wiki was always an incredibly useful resource in the past, and seeing it get shit up is really pretty sad.
