what you may want to do is come up with some "guideline numbers", of which help you determine if you need a template or not, and to an extent, whether or not you need to substitute or simply transclude the template.
This also raises questions, like:
* How often is the information across multiple pages?
* How important is the information to a specific page?
* Can the information be saved into a subpage of a specific main page?
After studying the information for a little while, i do have to say that the information is pretty organized, in terms of structure and readability of the information itself, and the use of sub-templating.
NintendoWiki has a similar idea, when it comes to sub-templating; however the games themselves would probably not be listed on multiple pages, so saving the information in a template would make little sense in that situation.
Similaraly, the
Donkey Kong Arcade Game is considered by me, both a game in the
Donkey Kong series and a
Super Mario series. So, to help with this, i created a
sub-page of the game's main page, in which imports the
same information but chooses a random color scheme to show for the infobox.
Hope this helps.
