New game categories and more templates.
It's possible to add other OS families - Windows is default if nothing else is supplied. |OSfamily = Mac can be added to change the header to a Mac category. We're in the process of implementing a [Template:SysReqMultiOS] template as well which we will roll out once it is complete.
I think it might be worth while implementing two types of templates. One for games from the 90s which had a single set of requirements and games from the 00s and onwards which saw a shift to minimum and recommended.
