What you’re seeing there is the inability of the combination of Mediawiki and the templating system to supply a sort key for games distinct from their titles. This is something I have hated for the entire time we’ve had the current system. The new system for displaying the module library has sort keys.
We’re in the process of converting the old module library to a new one, and you can help.
If you’d like to experiment with the new frontend, the code is here.
