I have now played both Warhammer Card Games (Warcry and Invasion). Just some thoughts on both:
1.) Warcry was an excellent game. Liked how "dice" were rolled in the game, and most of the high dice rolls were kept on less powerful action cards while low dice rolls were kept on more powerful action cards. It kept the game well balanced. Also liked the combat system...it had the feel of playing a game of Warhammer Fantasy Battles on cards. Possibly my favorite ccg.
2.) Warhammer Invasion, while lacking some of these, I believe is a better card game. Easier to collect (LCG), more strategy (need to balance out all three parts of capital) but still very easy to learn. While Warcry was simply just a "run up to your opponet and beat their brains out", Invasion has some of that, but you also need to be a "budgeter" of your resources, focusing not just on battle but building up your empire with smart resource allocation.
What do you think?
