Two dissimilar ideas:
1. Rolemaster had its famous hit location charts which were horribly destructive, and very descriptive. One reason is that many GM's find it hard to come up with interesting ways to describe attacks.
It is sad, but many GM's resort to 'you hit him with your sword'.
You could say that this is not necessary. That the GM if he really wants to could produce this, but I've seen GM struggle to produce any small amount of color. And most GM's I've seen don't have hardly any color.
Its not really that hard to get used to saying things like 'you jink left, but too slowly, and the bullet burns across your ribs'. A small example, and a little help may be all that's needed. Add in some practise, and most GM's should be able to make this a natural part of their repertoire, something that doesn't hardly require effort anymore.
Thus Multiverser needs some GM Aid, like a table, in this regard.
Now it is true that most players seem satisfied with less, but a well-done, but not overwrought and time wasting description of attacks seems preferable to the same players. Thus one is forced to chooe: same old slightly stale Wonder Bread, or a nice, fresh baguette from the bakery?
2. The Juncture Point is totally dissimilar. It allows the player to quickly hit the major points of a world's history, and interact with them while 'skipping the boring parts' as Zelazny described his writing style.
You could cover the centuries of slow growth between major changes. Or.....
The player has a conflict early in a world. He faces a sorceror or some odd tech. He wins, but the sorceror casts a spell to try to fling him into ethereal space next to the world as revenge.
The spell only partially works. Whenever there is a sufficiently dense tangle of world lines, the verser bumps against them, and is drawn back into the material world.
Another major conflict ensues. Possibly with the sorceror again who might be immortal, or might have been sleeping the centuries away.
Repeat and rinse over the millenia as the verser guides this world to a better design, and serves as the guardian angel of the planet.
Eventually the verser frees himself, or the end of the world comes.
One side note, this would allow the verser to see bias change in person.
