What is the best video game of all time? Also, what's your favorite if you make a distinction?

i think the best game of all time is the elder scrolls morrowind game of the year,this is a great game with hundreds of hours of game play,that's with out any mods,then if you add mods you can get thousands of hours of game play because there are lots of cool mods for it.i have a few games that i consider my favorites,gta san andreas,morrowind,are 2 of them.i always have a game save that i can jump into of each of these games when i get bored playing what ever im playing.hope this helps.have fun gaming.
