2014 was a fantastic year for videogaming, in therms of software. Many many great games in all platforms.
I wouldn´t choose MK8 as Game of The Year, but it sure it is one of the best games this year and a game that people will still be buying and playing years from now. A fun multiplayer experience like few games can provide.
And we still don´t know much about the download pack #2..... new tracks are coming, new vehicles. Who knows if they´re making something else in the future for it?
