Yeah, it seems to me that Alpha+3 kind of made it so Germany HAS to do Barbarossa instead of Sealion. I mean, Sealion is still doable if Germany is able to build up enough stuff and kills the Royal Navy, but with the new rule allowing Russia to attack when London falls, it will be much harder on Germany. At least with Alpha+2, Germany could have a round to build up against the Russians. I think that Alpha+3 kind of forces Germany into a more historical route.
