A discussion has recently been active over on Bioware's forums about which other games companies produce lithographs and other collectibles, and having looked around, it's fewer than you'd think. Fewer than I thought, anyway.
Does Larian have any intention of doing something similar with the Divinity series? Might it perhaps raise its profile a little? I'm guessing it's a risky venture as promo items are probably rather expensive to produce and quite a high risk: smaller companies don't necessarily have the money to throw at projects like this where they potentially have to write it off if it doesn't work out. Not everybody has EA's deep pockets, after all.
Still, it'd be cool to see signed lithographs made available whether from concept art or commissioning artists to paint key characters or landmarks, and "...bought the limited edition game guide" seems to be the modern gamer's equivalent of "...and got the tee-shirt"!
Whether or not it's likely to happen, I figured I'd just register a personal interest, anyway.
