It seems like 2015 is quite good for video games, we have plenty of successful releases but what was the best year ever for games?

My bet is 2007:
- Halo 3
- Call of Duty 4
- BioShock
- Crysis
- The Witcher
- WoW: The Burning Crusade
- Mass Effect
- Uncharted
- S.T.A.L.K.E.R.
- The Orange Box
- Super Mario Galaxy
- Crackdown
- The Darkness
- Persona 3 (North America)
- Metroid Prime 3
- Guitar Hero III
