I’m not arguing for anything in particular here, just thinking about how to make things work.
If we were to go the route of de-emphasizing game pages on IFWiki, one question becomes, what do you do when a game is mentioned on IFWiki? (For example, on a competition page.) Just make the game’s title plain text, with no link? Put in an internal link, but don’t put a wiki page at the other end? Or link to the game’s IFDB page instead? Then the person editing the wiki would need to look up the url for the game at IFDB each time a game is mentioned, instead of just typing the title in brackets. I wonder if there’s a way to shortcut that. I guess you could have a template that would automatically search for that game on IFDB, but that might be more annoying than helpful.
If some game titles are internal links and some are external links, is that going to confuse people?
I guess we could move in the direction of linking to IFDB once when a group of games is listed. If there’s a list of games authored by a particular person, you could link to a search for that author’s games on IFDB, and don’t link individual game titles. (Or maybe, in that case, you wouldn’t need to list the games at all.) Or if there’s a list of games in a competition, you could link to the competition page on IFDB.
