So should Minecraft and League of Legends be eligible for the Game of the Decade? Obviously, both were released in 2009, but both games were phenomenons of this decade, not last, and excluding them on the basis of being available for a few weeks or months last decade feels wrong. Maybe I'll make 'Games that received significant post release support in the 2010's' eligible for the awad.
League I don't know about but wasn't the "1.0" release of Minecraft this decade?
