The Top 7... in-game in-jokes

Inside gags, for better or worse, are a staple of videogames, whether they're in the form of hidden characters, outright parody of the competition or just another tired reference to Monty Python and the Holy Grail snuck in by a translator. If you're not in the know, most of them will shoot right over your head. If you are, they can range from dull to chuckle-worthy, but either way you'll feel a tiny surge of pride for picking up on them.

And then there are the geeky little references that are just kind of cool independent of whatever it is they're referencing. The ones that, whether you're geeky enough to get them or not, add something special to the game they're in. And in the case of this article, the ones you should get anyway, because they're referencing other games. What follows is a look at the very best of these, along with a bit of explanation for those of you who - for whatever strange, non-geeky reason - still don't get it.

After graduating from college in 2000 with a BA in journalism, I worked for five years as a copy editor, page designer and videogame-review columnist at a couple of mid-sized newspapers you've never heard of. My column eventually got me a freelancing gig with GMR magazine, which folded a few months later. I was hired on full-time by GamesRadar in late 2005, and have since been paid actual money to write silly articles about lovable blobs.
