After getting the name to one site, I've been able to use it find other similar sites:
Playfire - Looks to be too new, I want to be able to add old-school games.
MyVideoGameList - Same problem.
RFGeneration -
Almost what I want. Has a database of games (same as here), allows me to add them to my account, but that tool is more focused on managing your collection, whether you have the manuals, who is buying/selling, etc, rather than about actually playing them.
I do like the Backloggery concept of unfinished, completed, mastered, achievements, etc. I just wish the games were pre-defined. I need the guys behind Backloggery and Abandonia to join forces
That's my ideal tool.
