Never having played revised, although I have played classic and 42.2 so I can infer a lot about revised. I would say that G40 has a longer, more complex game with more depth. It’s the depth which makes Global better in my view. I can certainly see how World in Flames and Global War players see going to A&A as a backward step. The downside is that it takes longer to play.
Specifically:
- Scrambles
- Politics
- non automatic capital ship repair
- not having the AA Gun capturable
- arguably airbase & naval base movement bonuses
- arguably the inclusion of mechanised infantry
- note I didn’t say tac bombers
- note I didn’t say built in AA at facilities
Hope this is helpful.
