I just got about 100 hours on HOI4 and I cant play it at all. I have to date only won a single game (since I picked it back up recently after release), but typically the second I get into war my divisions lack organization, supply, or whatever else and I get capitulated pretty quick.

Are there any mods that take a single concept (supply, army planning, division designs, etc) and help you learn those in isolation? I watch a bunch of YouTubers and try to follow their tips but for whatever reason I am still doing it wrong.

Interestingly, I bought hoi on release and was able to world conquest on my first or second try, so I am guessing new dlc/mechanics (supply?) are probably part of the problem.

I am working on building a new server in my apartment that will have a reasonably beefy GPU and CPU so I can get PCIE pass-through working and get a gaming VM set up.

Trouble is, my apartment is in the attic in the south. With the AC on I had one or two really bad days last year that it got up to 90 degrees Fahrenheit inside with high humidity.

Any cooling suggestions for something like that? Is 90 degrees Fahrenheit still cool enough to reduce the temperature of my components? I would really like to avoid buying a phase change cooler, but that is the only thing I can think of if the ambient is too high.

Anyone seen any Android games that use Pathfinder 2e or DND 5e that let you use their battle rules to try out builds? Basically want to play a turn based game using their rules to test out character builds etc.
Anyone seen anything like that?
