Unable to find a single source listing of Commodore 128 (C-128) games, I did a Google search and Facebook post in the Commodore 64/128 group. I then took some time to compile what others had found into a single spreadsheet, which I can further modify as edits are inevitably required.

Here’s the link to the master spreadsheet.

Here were my references:
