Thinking about game logging sites… I quite like the look of Backloggery, and their cool web widgets, but… It just sorta has a different focus than what I have when I play games, you know? Backloggery focuses more on achievements like clearing out your backlog, 100% completing games, and stuff like that. I prefer the fairly recently created “alternative”, Backloggd, because it’s more focused on journalling and just keeping track of what you have played regardless of ownership, and logging your personal thoughts about a game.
Only thing I think Backloggd needs to be perfect are import/export options. I love me a spreadsheet! (And I love me the option to export my data from an online service, in case it shuts down)
