I got this a little while back, though did pay for it, albeit a tiny amount.
I was hankering for it ages ago after reading a massively positive review when it got released, but never got round to getting it. I've played a little bit but have had a hard time getting it setup to play with a 360 controller. Even then there are a multitude of extra buttons assigned to the keyboard and I need some sort of map to keep tabs on everything.
Have you played it on Windows 7 or newer?
Cool. I thought I might have to install to my old xp box, which I haven't booted up in months.
Some kind of sequel thingy "X4 Foundations" being flogged on gog's email newsletter ATM ("highest discount ever" er, for the as-yet unreleased game). Yeah like I don't have enuf games. :-S
