“Short” (last time I said that it wound up being 30 sessions) campaign inspired by Dynasty Warriors and Vinland Saga S1 about a civil war that breaks out after the death of a young king leaves no clear heirs to the throne. Breaks down into civil war with around 8 factions. Game clearly divided into 3 parts:

• Combat, where PCs engage in small-scale fights, mostly for 1v1 duels with enemy generals
• Tactical, where the PCs move troops and generals around a battlemap, single roll combat for each front. Zooms into Combat when two generals meet.
• Strategic, where the PCs negotiate, spy, and generally try to win over other factions without fighting. Zooms into Tactical when a battle breaks out with another faction.

Rules will be very simple. Players will choose one skill for each part of the game then split points between them as they choose, so you could have Greatsword (Combat), Reckless (Tactical), Intimidation (Strategic). Probably going to have a slight rock-paper-scissors system for each part where eg melee weapons are better against ranged are better against magic etc. Each PC will probably get a retinue of minor NPCs for the other players to take over when their main PCs split up.

Fantasy setting, no real details other than that it requires a decayed central authority. The 7 non-PC factions are at most just fantasy tropes in my head atm, eg the church, the elves, 2-3 dominant noble houses.

My other, even less formed idea, is “D&D but with diegetic levelling, which only affects the PCs and a handful of super-powerful villains”. Partially inspired by Baldur’s Gate 3 (where being a level 12 murder machine wasn’t really recognized by the narrative) and Kill Six Billion Demons.
