Dan was insisting that every replay had to start from the beginning.
So that this means every node has everything correct.

From my view, most of the information is unnecessary, and useless after any given time.
Things like HP or MP are important while in a fight, but the next day, none of that fight mattered.
(yes, death, loot, exp gained, weapons broken, are all important, but they are a tiny fraction of the data involved)

And, as a game gets older, the chain becomes extremely large, and replaying becomes a very hefty price.
and most of the information is useless.

So, i suggested having saved points, or just resetting things like HP and MP and/or leave them out of the block chain.
