I was going to do this the other day... but wasn't confident enough to hit that post button. Today is different though.
O.K. so, in my opinion games are just as relevant a form of media/entertainment as film, music, books etc. Indeed, there have been some beautiful pieces of music for games.
It doesn't have to be a new game you can talk about here, as there are many classic titles people still enjoy and which are available to people via things like Xbox Live etc.
While games have taken more of a multiplayer approach because of broadband, single player titles are usually the ones offering more in the way of atmosphere and/or great artwork so whatever you've been enjoying please feel free to mention what it is and why. Or if it's something you remember then mention it anyways!
