I did the same. Played 8 or 9 hours (got about 1/2 through the game), then started playing other things. Once they get everything ironed out with Joysticks it will be more than enough for me to complete it. Right now they are working on sensitivity tweaks and a few other issues brought up in the forums. Including mine, which is quite frustrating: If I stop my T.A.R.G.E.T profile and restart it, the game seems to not recognize the inputs and I have to remap them (they get renamed). So, basically I must set up my controls each time I play.
I am personally going to wait a couple days/week to give them time to hammer things down. Just figured I'd share the news.
