I just got a copy of BRIC today...
This is essentially the same as the Sino-Russian Pact WWIII scenario that came with the KS games. Both rulebooks include both scenarios. The major rule change is that in the newer rules Iran, not India, is a member of the BRIC Bloc.
Kick Starter Backers:
1 - If you want the new rules, CPG will send you a free PDF. But if you are a "comletist" you will want the actual rulebook (CPG will probably send you extra dice or GITD clouds in place of the minor armies/navies you already have).
2 - Hold on to your Sino-Russian Pact rulebooks!!!
CPG will probably not reprint the older rules, so these are collectible and very limited in production.
