Quoting Suomi Sotilashenkilo,
Although most of the stuff I've seen from the Crusade journals is pretty great, there is one really big thing that does worry me:
I've always hated abilities that disregard everything about the game and everything you've been trying to do; I hate auto-win buttons and abilities, no matter how expensive or potentially damaging their use might be. I can appreciate heroes making a fleet better or giving it an advantage, but not auto-wins. That is one thing I need to be able to turn off.
It reminds me of how in Empire at War: Forces of Corruption, if the Empire built the death star there was only one way for the Zann Consortium to defeat it. It resulted in the death star and its entire escorting fleet being obliterated, at the cost of losing a hero permanently (although the death star was also permanently gone) and losing a bunch of money (but that's set against a death star and a crapton of wasted construction time).
I hate those sort of mechanics, where no strategy or conventional advantage can make a difference because the ability is unstoppable.
I'm willing to pass judgement on this one until I see the costs involved.
I imagine that the martyr ability, along with the other "auto-win" abilities will require super-rare resources, resources that you might well either not have, or need to use for something else equally game-changing. That would fit with their apparent goals this time around.
Also, wouldn't it be just sad, if you were the only one in the galaxy who had said super-rare resource?
