Fortunately for me I'd already gotten DXHR way before that but it has to be maddening for people who didn't because it was taken off Steam once DXHR:DC was released.

This strategy with Mankind Divided isn't new. If memory serves, SE did the same when they released Tomb Raider back in 2013. People who were already set on buying the game regardless might find it a plus but I sincerely hope the rest don't just buy the game because of this KS pre-order bonuses. I mean, we don't even have the specs yet! Personally, stuff like this only encourages me to wait until a more complete edition is released or until it goes on sale.
