Yeah, I don’t like options 3 or 4 either. But they are possibilities that could be used.
The PA or PE bids are the most conventional strats and generally both seem to give the Axis a good chance at winning.
With operation sea lion, I’m not convinced that it is an automatic win because I think Russia will be all over Germany and the ipc’s Germany gains by the UK will be needed to keep the US out of England. But I haven’t played this strategy enough to really try it out.
With rolling for tech, you are right, Germany had better get lucky soon with this. I think this would make for either a very short game (Germany doesn’t get IT) or a very long game (Germany gets IT). Again, I haven’t played this enough to really know how well it works.
Feedback on these is a good thing because even if an idea is half-baked it still might be fun to try sometime 😉 .
