I'm interested in all fronts, I like to be able to switch around when one gets too stale - I hate the Yak's because their armament is crap for the most part. I like the I16s though, early LaGG, and early La5. I think it's the asymmetrical line up of the single MG in the Yaks that really gets me, throws off my aim for some reason.
I like Carrier ops, and the Pacific is an interesting theater. Not to mention several of the planes in the Pacific are Lend-Lease on the Eastern Front too - A20s, B25s, early P39s, early P40s, etc.
Now, I wonder if we are going to have the current US aircraft after the next patch...
