No, I'm not one of developers; the developer is the Unicorn studio from Ukrainia. I'm only one of game supporters (from more than a year, before with Death or Glory, now with Blood of Europe, in future with Real Warfare 1242 and Lords of War): actually I spoke with the chief developer almost each day (it's on steam each day :) ) is a very friendly guy, which love much his work and trying hard for implement the better in his engine.

Just to be clear: the videos are made with XIII century Blood of Europe and already out game (you can purchase him on steam or gamersgate, or on amazon). The futures releases will take the name Real Warfare. the first will be 1242 substantially Blood of Europe + 1 new single campaign (actually the campaign are a succession of thematic battles) and after Lords of War (next year if all go ok) with a true multiplayer campaign (described above), sieges and naval warfare. Personally I suggest, if you like especially the tactical battle, and especially the hard tactical battle, to purchase Blood of Europe in waiting phase of Lords of War.
