If you do end up perhaps compiling something like an excel document with multiple sheets (1 for each console) showing various information for each game on the console (hopefully including all games), it is definitely something I would be interested in having for reference.
I currently have separate spreadsheets for each system I own (and a few I want). The game list is currently limited to the games I own or want, but I may some day expand it to complete game lists if I ever decide to expand my passion for game collecting to include complete system libraries. The information for each game currently includes: Game Title, Region, Availability (Do I own it, is it digital, is it CIB), Art (Do I have custom art), Manual (PDF or paper), Save Type (work in progress), Rarity, Rating, Genre, Developer, Publisher, Release Date, Series, # (in series), Also On (Other releases or exclusive), and additional Notes. If the game title is Japanese I have and English translation noted. Some of the lists have system exclusive information such as control scheme (for Atari & Wii), Game Genie codes, Price, or DLC. Some of the spreadsheets are still a work in progress, especially for those systems which I do not own, such as the Neo Geo or Intellivision.
