Well the one for 200€ is just a headset with the phone included so I doubt the grafic will be anywere near to the original Rift in the next few years.
But yeah the Cable and sensors are a little bit problematic.
I had to adjust my whole room because the Sensors only have abour 1-2 meter Cable (not sure how much exactly) so I could not put them wherever I want, would have hoped that there are 10m cable or that they wouldn't need to be connected to the pc so that I could have put them on my TVs usb :/
Online some people wrote that not all extension cables would work and those that the people suggested (usb 3 with amplifier) are kind of expensive ...
The Rift has a 3 meter Cable which can be extended as well but with even more problems, needing special cables (seems some cable do work with some grafic card and the same cable wont work with another so its very bad and you need to test with some different settings) still for me after adjusting everything in my room it works fine. I have about 1,5m left and right and 2 meter back and forth.
When playing sometimes the cable is slightly in the way but most of the time I don't notice it !
There are not that much great games but some like Robo Recall are AWESOME !!! and the free short videos are nice too ^^
Even though I am playing a lot and even had a friend stay over for two days at the weekend we could not try all the games and stuff I have yet. Especially cuz my friend was so fascinated by robo recall that he could not stop playing XD
Oh yeah and Luckys Tales is sooooooo cute, must play for everyone who likes cute foxes and super mario. This game plays really well in VR and the level look very good so far.
But one Problem remains, after like 30-60 minutes I feel kind of exhausted and thats not only because of the way you play but also because this VR stuff feels like its hard on your eyes and you are to much involved sometimes. After playing to long my friend and I feld like we still are in VR while sitting in the pub drinking some coke.
Oh yeah and some games give me a very bad motion sickness or VR-Sickness

I guess I might not use it much in a few weeks / month but that happens with like everything sadly ... for now this thing is completely awesome.
