feel lucky today ?
The game's a nice idea altogether, makes me want to replay the "real" cthulhu game :D
But the balance of card effects has to be worked on. The whole system as it is right now is almost reduced to base on luck. For example - the challenges. You have 10 life and need to fight an opponent with 4 times as much. You start, have no healing card, your opponent plays a card giving you a 14-damage-clout, you die. Happy end. The challenges are ridiculous. The main game presents itself better - but still you need to rely on your opponent's stupidity. I love to see, when I force him to discard a card he could have used some turns before to defeat my ass.
What I also consider a bit unbalanced is insanity. In my opinion Xenophobia is a blessing compared to Megalomania. Who needs a weak monster, that doesn't attack, if one can just toss around spells doing far more than 10 damage? - without fearing insanity costs of course - because it can't get any lower than -10. I would employ MORE side effects with advancing insanity, whatever, but NOT just stop counting at -10. Or stronger monsters, maybe some which cannot be banned. Whatever, just something to restore balance and strategical thinking.
p.s.: in "CoC: dark corners of the earth" you don't stop being insane at a certain level. if it's to much, you commit suicide.
