I'm a big fan of BRP in general and especially of Mythras.
I'm curious how well it scales up in power - I know that Mythras can do gritty, "Sword and Sorcery" style games and historical stuff really well, but it seems (to me at least) that it seems firmly rooted in a more "Human" level of power.
Can it scale up to a more epic level of power? Where do the break points kick in? For example - I was a big fan of the old Unisystem Witchcraft/Armageddon Games and ran a very successful campaign using that, but it featured Powerful Mages and Demigods fighting against Cthulhoid minions
