It is good to see people coming back to the game, yeah! I think I'll definitely try some of the newer quests without some of these cards, in the hope that I might actually get to stage 2 of some quests.
There's a wonderful document on the Arkham Horror support page where the game's designers share some of their house rules and other thoughts on 'amending' the game in various ways, either to make it more difficult or less so. Somewhere in there, they say something like 'the goal is to have fun, so do whatever you're comfortable with', and that has become something of a mantra for me with all the games I play now. It is all about balance, of course, rather than making a game so easy it provides no challenge and you know you're going to win before you open the box. Maybe it's the GM in me coming out, but I value flexibility in a game to keep it going and to enjoy it. I go to work to be miserable, I don't need any other methods of achieving miserability! With this new variable difficulty mode I think the designers have make an excellent step in that direction - and unlike the Nightmare decks, it doesn't cost a penny to play easier!
