For me, it's gotta be the Xbox 360. For me it even beats every Nintendo system except the SNES and Wii.
It just had so many awesome games, from Gears of War 1-3 to Halo Reach and 4, Bioshock 1/2/Infinite, Witcher 2, Bayonetta, Vanquish, Mass Effect 1-3, Dead Space, Skyrim, Wolfenstein The New Order, I could go on and on.
Add in one of the most comfortable controllers of all time and you have one for the hall of fame.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
