I know the game is practically ancient at this point (2009, apparently*) but Eador: Genesis is 59 cents at on GOG right now. I was thinking of the game for some reason and googled up some screenshots (mostly for nostalgia’s sake) and noticed the sale.
This game is just so damn good, it’s hard for me to express the absurd quality per penny ratio here. And the original (arguably) holds up better with 2D graphics (though the 3D remake did tone down the Russian-level difficulty a bit).
*Something like 2012 feels more correct to me–maybe the English translation happened then?
