It would be really nice to be able to flag a game for a particular reason, like "This is one of my cool games". Something like that.

Currently, you could write up an article about a game and include it in the article, or even a link to a game, but I'd like to simply be able to categorize my games for my own review, or somehow set aside my "memorable games". Make that list public or private.

This could be as easy as putting a combobox next to the entry in the game list.

it could later be expanded upon by letting the user put public notes on each game, or be able to give each game a "favorites" title.  

Again, you could easily type all that up in an article, but not all people are wordsmiths or even want comments on their game.

A quick & easy concept like "favorites" can go a long way with a minimal amount of work.

good idea, i have a few faves i'd like to highlight
