Hmm, don't take that personal, but I didn't like anything :(
The only thing I was able to test was the "3rd Person Controller + Fly Mode" which is just one of the assets, I wasn't able to get out of the tutorial(which I think is just a demo of this asset) (from comments below I thought that by pressing ESC I would be able to get out of it, but it doesn't show anything :/)
So...based solely on this experience...I wasn't able to rate anything else, sorry man, I don't know if I have to execute all commands of the tutorial (mouse wheel is broken, so...) but at least for me it wasn't a good experience.
Although I really hope I could play it better.
