Wow really? What led you to choose the PS4.
That's kind of a difficult question to answer. Firstly, I feel like I need to explain why the Wii U never seemed like a viable option for me.
Over the course of the Wii's lifespan I became dissatisfied with Nintendo and their inability to meet my appetite for games (both in terms of quantity and breadth of software), something which I feel was exacerbated by the very obvious limitations of the hardware itself. Put simply, I became increasingly frustrated with how oblivious Nintendo had become to what was happening in the rest of the industry. It seems to me that with the Wii Nintendo walked into a technological cul de sac and in so doing separated themselves from their competitors and from the tastes and expectations of a large proportion of gamers. The Wii was certainly a short-term success, but longer term I feel it will prove to have been detrimental. Nothing I have seen of Wii U has led me to believe that this trajectory is likely to change.
As I've said many times before, I really don't have any brand loyalty. My commitment to Nintendo consoles has always been conditional.
Xbox One was a consideration, but for me Sony has just made a more convincing case that their platform will suit my tastes. Although I've only ever appreciated it from afar, I really love what Sony has done with Playstation Plus. I dig their apparent renewed commitment to Indie games, and I've also always felt that Sony have the capacity (if not always the will) to get behind quirky games in a way that Microsoft might not.
I will, however, admit that historically I've never really enjoyed those games which Playstation fans hold dear. I hate Metal Gear Solid, Resident Evil and Crash Bandicoot, and have never played the likes of Ico, Shadows of the Colossus, or Heavy Rain.
To be perfectly honest, much of why I'm choosing PS4 is based on speculation.
