Hi guys, I often have wished to ressurrect one of my oldest campaigns, which used AD&D 2nd edition rules, but in a different ruleset.

The game world was a detailed homebrew threatened by the appearance of a chaotic evil entropic force (not really a god), which was channeled into several mortal proxies throughout the world in order to create an apocalyptic event.

The forces of Good, knowing that some unspeakable acts would be necessary to slay these proxies, recruited and empowered the nastiest, most powerful, Lawful Evil individuals, the PCs, which started at 12th level, veritable one man armies.

The game was a troupe style epic semi-sandbox, as there weren't really missions, just the knowledge of impending doom coming from unknown places, and the dark champions would more often than not work alone, or with followers, rather than together.

As I don't think AD&D 2nd is really a good system for epic, cinematic, games, I was trying to figure out a replacement, although one that didn't deviate too much from a D&D feel.

At first I thought about using Legends of Anglerre, but was thinking maybe the new 13th Age could scratch that itch (if it isn't too clanky with 4e-ness), or maybe Savage Worlds (but that could be too far from the original experience).  What do you think ?

Stormbringer!!!

B/X D&D or Labyrinth Lord.

Stormbringer 5.
Or more accurately, the forthcoming Magic World from Chaosium for BRP.
Big, epic, slaughterful, an allegiance system that isn't alignment but handles Law and Chaos well (rewards you for following your allegiance).
But if you are cool with second hand, pop a search on ebay for Stormbringer and/or Elric!.
I'd not go with the Mongoose version personally, SB5 was and is the best BRP iteration for the sort of game you want and already has all the Law and Chaos stuff explained for you.
Actually, any version of Chaosium's Stormbringer will make you happy, the last one is the GW version and is great fun, very useable and easily found for nowt in the UK.

Here;s what I found on ebay.

Thanks for the replies, I'm sure to look into Magic World when it comes out.

Fantasy Hero as the powers system allows you to fine tune the level of epic magic you are going fore.
