its available digitally, i have it on steam but unfortunately this is all to familiar a tale with retail RPGs on PC for us Brits the last couple of months.
The UK's one of the best non-German or Polish countries for games, y'know. But at least it's applying to most countries and not just us.
It's not too uncommon for smaller publishers/developers to release physically after a digital version - 1C/Focus do it with King's Bounty. I got the digital version of Armored Princess months before it'd hit the shelves in the UK (And I think it must have been a year before the US, possibly), and Crossworlds is yet to be seen in retail form, but I've had it since it released digitally.
That said, I thought ArcaniA was out in retail form. How odd.
