Diary entries chronologically
I would love a diary like the one for movies on letterboxd.com,, where you can just rate the last game you played and it will put a diary entry with when you played it (maybe even the time period you played it). At the end of the year you can review the year and see which game was your favourite.
This site has enormous potential as it resembles letterboxd which works so well for movies! Would love a site like that for games which also is all about style.
