It sounds like the outcome is inevitable. A combination of losing Egypt and Germany still having 11 Air, leads me to this conclusion. To have a chance, Germany needs to retain its advantage in Air units, which it has done. With Egypt, the Axis have the final VP needed for the Axis and the added income for Italy.
I presume the Allies still own Gib. Is it worth the UK building an AB there? This way, the US can safely land in Morocco. Remember that German Air hitting this fleet would mean the end of the Allies’ chances. Ensure the Axis cannot attack SZ91, by landing in Algeria. This can happen , if the Italians can take it before the German go.
Regarding Egypt: did that fall on I1? Was it a mistake in not blocking both SZs in front of SZ98? That can happen, if the UK’s two units (Cruiser and Ft) are eliminated by the Tobruk DD. I am happy to empty Egypt on UK1, knowing that SZ98 is safe. The UK has to be aggressive on R1. Perhaps, bad luck was the factor and victory cannot be achieved, as you suspect.
It has been a few years since I played Europe (alone), so I do not want to suggest a bid fir your next game. I thought I remembered that the Allies did win some of our games. Consider hiving the Allies a bid, if your Axis win a couple more times.
Good luck and enjoy your games.
