I agree, it would be a better idea to link to their Wikipedia pages and for users to update these pages. There is no need to repeat what has already been written. The majority of the developer and publisher Wikipedia pages are already comprehensive.
Could attempt to try this: http://en.wikipedia.org/wiki/Interwiki_links
I am in agreement with you both about posting the 'history' and 'news' of a developer - not relevant to fixing games.
Is there an argument for a page (like Valve's) where we can list all the games that they have developed? Or we could just replace it with an interwiki link (extension is installed) to their Wikipedia page: http://en.wikipedia.org/wiki/Valve_Corporation
Wikipedia does not list all the developers and publishers. I don't see anything wrong with having a developers and publishers page which list all the game they have developed/published. It will be informative.
If people have information on developers, publishers and games which do not have Wikipedia articles, I think it should be encouraged that they contribute articles to Wikipedia.
I'm in favor of making the developer and publisher sections of the infobox of an article into an interwiki link. Anything else just adds non useful clutter to the wiki.
Yes this will be the best option going forward in my opinion as well. We can delete developer pages and use interwiki links.
Thunderbolt and Newmansan, you have both been very active and extremely helpful on the wiki in the past few weeks. Please email me at firstname.lastname@example.org if you are interested in helping to moderate. This will also allow you to edit the Infobox, approve revisions and delete pages.
