I started the thread on the Danny Variant Set over at Board Game Geek a while ago. It is a collecting together of several variants with adjustments to make them work as a cohesive whole.
The variant leads to a final crisis at the end of most games, unless the players did really well, in place of the normal "fight the GOO" system.
Also fewer doom tokens build up early in the game but things get nasty later in the game.
If anyone here plays a session with this variant set please write it up and link to it from here.
thanks
