I bought the Horizon bundle but haven't even tried it yet, been having far too much fun in Pavlov but I've also tried a bit of the Star Wars demo which, even as someone who isn't a Star Wars fan, was really cool.
I'm very impressed with the whole thing, the set-up process was great and the experience is extremely polished. I have got the Sense charging station coming as a birthday present though, I resented the price before but charging the controllers individually is quickly going to become a faff and their shape makes them awkward to put down somewhere.
