Seems solid, who could argue with artillery? Its still my favorite unit since revised :-D
The carrier is fun though, if you want to force a naval arms race. I think it works in principle, but really only if you’re willing to outspend the Allies on the water early with the whole Axis side. If you can catch them off guard or throw them off their purchases for a round, its possible to maintain overall naval parity for good part of the game with the Axis side. Just having a decent Baltic fleet or ships in the med is always enjoyable. Everyone dreams of the dominant Kriegsmarine, breaking out and wrecking hehe. I give G40 credit for at least making the Graf Zeppelin workable in this game.
It has strong entertainment value, even if there are other plays that work too.
