Great discussion above. I was going to contribute but need to absorb what has been written recently.
Keep watch the vids as other things will develop that need attention later. I don't want to give spoilers but look at Malta.
Malta in WiE/WaW observations:
Now in the old days when planes could not do missions because of rain, etc...Malta could get a rest and slowly recover, at least from air attacks. This also included a potential para drop if the AA unit was destroyed and Malta was empty. There were many times when as Allies..I was able to slip in a new unit into Malta if a port was open. Another thing some of us did was house-rule 'No Railgunning of Malta'. RG's have a range of 3. That's fine for something like Sevastopol or Leningrad. But Malta is an island and not like a hard point easily targeted like Fort Maxim Gorky at Sevastopol. One thing is that Malta is composed of a variety of sedimentary rock, easily dug for entrenchments and fortifications.
Malta with TRP (past versions and current version):
Past Version 0.9.7 observation: So last year I tested/played an MP match with Unfortunate Son with v.0.9.7. At that time, air attacks were not possible in rain, etc. Now we had also House-ruled no Rail-gunning of Malta as we both felt that was unrealistic. Also at that time, the AA unit (Crispy131313's Fall Weiss II DEC adapted to TRP) could be a 13 strength AA with 3 experience pips. So bottom line, Ray (Unfortunate Son) repeatedly attacked Malta by air. He did severely reduce Malta and the ports by air and occasional bombardments by sea. The thing was bad weather did intervene at times, that stopped his air attacks. This helped the AA unit recover. Eventually, he had to leave off of trying to take Malta when the bad weather became consistent come Oct 1940. We did have quite a few naval engagements, but again weather was a factor since the Luftwaffe was grounded at times because of weather.
Current Version TRP 1.2.2 observation: (Warning Spoiler for Duedman's and my vids on YT-but I think this is important to bring up now both for SP and MP play of TRP.)
Malta goes down in 4 turns.
First, a rail-gun with all it's shells are used on Malta from Sicily. (I had forgot to ask Duedman if we should house-rule out 'No Rail-Gunning of Malta. No critcism of Duedman btw.

The full force of the Luftwaffe started to bomb. Upon Valleta going down below 5 supply, and the 12 strength ports dropping to 5 strength instantly. (not sure of the cause exactly..there was only 1 Italian sub on each port.)
I could barely reinforce the damaged 11 strength AA unit on Malta. It was de-trenched immediately, (Valleta max entrenchment of 3)
Because regardless of weather, at the time, all weather medium bombers could fully de-trench even in rain. *Not an issue now with the newest patch-a huge improvement tbh.
Regardless of rain or not, an airborne unit could land on a vacant Malta.
Conclusion regarding TRP and Malta. Even with the new patch that eliminates de-trenching by medium bombers, Malta is still very vulnerable to being taken by the Axis. Main reason is double the turns to do so. In vanilla WiE and WaW, the window of opportunity to assault and take Malta is alot shorter. Also, in my opinion, the max entrenchment is too low. In addition, the fact that the AA Unit can only by DEC be brought to elite status of 1 pip to 11 is a detriment. Not sure how to fix the latter as I do like the idea in this later version of TRP to let Hqs get up to 5 Pips of elite and combat units 1. I get the design decision here. But apparently Malta was forgotten.
Now I don't want to see Malta totally invulnerable to an Axis takeover, but as things stand its a pushover for the Axis.
So on Duedmans and my TRP series on YT...the 4 episodes that feature this will air starting on May 31, 2023 (Episode 27). I would strongly urge that these vids be analyzed by all to perhaps figure out some kind of balance. I understand that SP and MP balance is different overall, but believe even for SP, Malta defenses need to be stronger. I have ideas but would like to hear what others have to say.
Sorry about the spoiler but since I saw Dave (Lothos) considering changes...I figured I should put this up now. Its only a little over a week away before the initial Axis attacks on Malta, so folks won't have long to see what I am talking about.
I love this mod btw...but I gotta call a spade a spade when I see one.
Cheers
