This isn't a one-off. It's merely yet another year where Disney dominates the box office. Any one of their divisions can give another studio a run for their money. Together, it's more like Voltron against a MS Leo.
Fantastic Four has been confirmed, but no details or date yet.
Given what Far From Home is pulling in on top of Endgame's box plus Carol's take home, dump truck of money is a trivial expense recorded under petty cash right now.
For M&M in a non-supers, I tend to use True20. I'd really like it if that could get an update.
More on the OP's question, a friend and I used Alternity for everything from late medieval to cyberpunk, and he brags of having used it for a caveman game.
Welcome to the joys of modern game design. Where trying to make it all make sense just makes the wine merchant rich.
If you're already using AnyDice, you should be able to figure out how far you need to drop the DC so the two systems are weighted about the same. From what you say, try about DC18.
It's not a joke, just specifying the territories. The Prince of Wales is the ruler of Wales, the French Dauphin ruled the Dauphine (and as a more absolute monarch than they got to be when promoted to le Roi).
No, it's not, Since about a third of the modifiers apply to the DC, not the roll. I think Gridlock's system looks OK, since you can move the default DC up or down to determine the campaign feel--something more like an Errol Flynn action-adventure movie might be, say, a DC 15 game.
My guess on that front would be that Barry learned something about Lu relocating Klaus, and maybe guessed they were working together. Or maybe that he was still tagging after her like a puppy-dog (it seems a lot of other Sparks did so).
Given the way contracts were used back then to take advantage of people's need to appear patriotic during a war, his contract was likely for a dollar. Flat fee, nothing on-going, no residuals, done deal.
