I had the 360, but it was still clear for me that I would be buying PS4 only. The lack of games in the last few years led to my 360 collecting nothing but dust, same as the Wii. For the PS4 the strem of good games just didn't want to end so I played it on a regurlar basis. The Vita is collecting dust though...
I almost bought a Wii U the other day, they had it at a local dealer for 149 €. It was too cheap to resist. But I found not one single game that I could play. 69 € for NSMB is a little too much in my book. they had Darksiders 2 for 25 € but I can get that on PS3 for 10 €. Zombi U was there for 39 €, but I'm not really interested in it. I thought about Virtual Console, but didn't find any Nintendo Pre-Paid Cards. So with not a single game that I wanted to play, I just said "fuck it" and went home.
I wasn't really interested in the Xbox One but some good games could have changed that. But now even good games won't change that I'm not going to buy the console. I'm still waiting for Internet to arrive here and mobile just isn't really a real alternative. If I use up too much data, my speed goes to shit. I can't even log on to PSN anymore so I imagine there would be times when I can't play Xbox One for about a week or so. I also tend to buy used games a lot, especially older ones.
In the end, I'm heavily Sony biased, as I like that company not only as a console manufacturer but for virtually any product they release. I really like their design and the quality hardware. That's why I own a Sony Vaio, a Sony TV, an Xperia Z Smartphone, an Xperia Tablet, a Sony Smartwatch, a Sony Camcorder... you get the idea. But still, normally I'm a Multi Console Player. I own PS3, 360 and Wii. But the Xbox One is just a real mess if you ask me and not attractive at all. The Wii U just lacks any games that I want to play.
But yeah, all I have to say in Xbox One threads are bad things and I really like the fact that people are turned off in masses from Microsofts "you don't own anything at all" approach. It just shows that people have common sense. And I also want Microsoft to fail so that the future of gaming is somewhat saved. They don't have to get out of console business, but they should make a better console for the 9th generation. The only language they understand is money. That's why I'm voting with my wallet.
