All HOI5 needs to do is make a game the AI can actually play
The current state of the AI in HOI4 is just unacceptable for a game that’s been in development for over a decade. Even the most basic stuff like division/tank/air templates is a total mess, yes you can make a “historical” argument but against a play who knows what they’re doing everything the AI builds just melts against even reasonably competent templates. It’s totally unacceptable that it takes something like Sheep’s mod to get the AI building templates that are actively competitive in the context of the game, even if you wanted to include “easy” or historical designs that should be configurable through game settings.
When we get to the more complex stuff the AI is just objectively broken. Go load up a Japan game and tell me if the U.S. AI can get anywhere close to a reasonably competitive Navy against you. I’ve run games to 1944, tagged switched over to the Allies, and seen them building 1936 carrier designs. Half of the mechanics in the game aren’t even used by the AI, I’ve never seen it intelligently use spotting/NAV aircraft against me and when was the last time you saw the AI pull off a large encirclement maneuver against you?
95%+ of the player base plays HOI in SinglePlayer, it is absolutely reasonable to expect the AI to be able to use the basic mechanics of WW2 combat like encirclements instead of just pushing their entire line of infantry against fortifications. Hamfisting “fixes” for this like giving nations an absurd amount of manpower isn’t really a fix, it just papers over the fact that the AI has no idea how to coordinate a push against an enemy line which should be one of the most basic mechanics in a WW2 game.
How does HOI5 fix this? I’m not really sure, but mechanically everything it builds needs to be designed around “how do we make a game that the AI can sustainably play”. Just getting countries to play the game at the level of a player with ~50 hours of experience would be a *massive* upgrade over where we are now
