Basically, a button that would show up in the same bit as the Download buttons, where, when you finish the game you can cheek the box. For those that like to know how many times they have finished it, have a type box so they can put the number of times they have finished it in as well, then you could have a global stat thing that's says how many times people have finished a game. Or something.

Half asleep here, so sorry if it sound incoherent. lol

I use 'Hide game' for that purpouse, although it does not count anything like a number, but it does the job of having two different categories in my Game list.

That's a nice idea.

Same thing here, though yeah, it would be good if we could add some sort of "Game finished" badge or something like that to our games
