Very few people are actually talking about taste...
Nintendo typically have more exclusives but people are acting like PS4 and Xbox have no more then 1 or 2 exclusives announced for future. For secondary consoles it all comes down to who's exclusives you're next eager to play and thats entirely down to taste. If you don't like platformers half of the Wii U exclusives immediately become irrelevant. I don't like racing games so I never acknowledge exlusives like Drive Club or Forza...
Whether you game on PC or care about last gen releases may affect whether you view some of XBO/PS4 titles as exclusives or not. I don't game on PC, nor am I interested in buying last gen console releases if theres a shinier one out there.
Bolded means I'm actually interested in the game.
