Of course, should be the deciding factor in the first place the games and here I was totally convinced. Who loves car racing games should really anschaun the Forza games times closer. That just insane temper and thanks to the good server from Microsoft the multiplayer part is also a treat. Have on the PS4 and Drive Club can test for comparison, first is also fun but is just boring because not as extensive. Multiplayer unfortunately I could not test on the PS4 because the servers went on strike and no login possible.
Conclusion:
For fans of the exclusive games such as Forza, Halo, Fable, Sunset Overdrive etc. a mandatory purchase.
For fans of the PS4 exclusive games such as Club Drive, Killzone, Little Big Planet, etc. I would recommend the PS4, but still waiting for a more favorable price or even a Slim version, which will hopefully be quieter.
For those who do not make the console purchase depends on exclusive titles, the Xbox One has in my opinion the better overall package. Although the PS4 can more pixels represent but a difference I could not see (42 "FullHD TV at 2m distance). The Xbox One has it a little more CPU power and provides developers a little more RAM available. The new Assasin's Creed Unity running example on PS4 and Xbox One in the same resolution only on the Xbox One just a little smoother. In a nutshell, the performance difference is not noticeable, therefore the quality of the Xbox One convinced me spend more because nice and quiet, super controller without squeak or rubber wear, 1 year extended warranty and more features such as Media Player.
