You make fair points, but I think Larry wouldn’t think A&A is disrespectful. In fact, it seems he views it as an outlet for his deep respect of the WWII generation.
Alternate history (like Amerika) is a finer line, I suppose. That is speculative, but ultimately serious.
Zombies just seem to cheapen the whole experience. My opinion, of course. Perhaps it will be the most fun and engaging of all the A&A games … I just won’t find out. Interested in seeing what everyone here thinks, though…
