This idea reminds me of the US Entry Rules for World in Flames. It’s been probably 15 years since I last played WiF, but I remember that there were specific Axis actions that triggered the US player drawing a chit, and when the total exceeded a certain number, the US could declare war. Personally, I think a system like this is much better in that it introduces some uncertainty into the game. I’ve only played two games so far, but in both games the Allied player maxed his factory builds to get into the war as soon as possible, and the Axis attacked the US on the turn the US could declare war. That’s just a little too convenient for my tastes. With an uncertain entry the Japanese player has to be a little more honest – wait too long to spring that Pearl Harbor attack and he may find it’s too late.
I’d like to see some discussion generated on this topic. Surely I can’t be the only one who thinks this is a good idea, and I’m sure with some brainstorming that there could be more ideas for events that would trigger a US card draw.
One other suggestion I’d make is that in addition to the 2’s through 8’s I’d leave in one ace (1 point) and one joker, which would be worth, say, 10 or 12. This would increase the randomness even further, though the odds of drawing one of them would be small enough that it shouldn’t throw things too out of whack.
