This week has been filled to the brim with gaming-related news, thanks to E3 2014 over in Los Angeles. There were plenty of new game reveals, announcements and previews, including some that to me look especially exciting: The Witcher 3, GTA V on PC, Far Cry 4, Uncharted 4, and a new Tomb Raider game just to name a few.

It got me thinking, though, about which game is the best I've ever played. I've certainly played more than just a few games over my life as both a PC and console gamer, and each year you get blessed with a number of absolute gems that would make it up there as an all-time favorite.

For me it's probably a toss-up between Grand Theft Auto: San Andreas, the original BioShock, and - undoubtedly a recent classic - The Elder Scrolls V: Skyrim. But I'd like to know what you think too: what is your favorite video game of all time?
