So my regular opponent @The_Oni_of_Hindsight and I began discussing the 2025 Metal Head Armory (our local gaming group) big game. Last year was Horus Heresy 12,000 points a side

• Ravenguard (Supreme Commander-Me)
• Adeptus Custodes (@GameRanma)
• White Scars
• World Eaters

Traitors

• Iron Warriors (Supreme Commander @The_Oni_of_Hindsight)
• Word Bearers
• Demon Army
• Dark Mechanicus

This year we are discussing doing a large scale 40k game. It is the early stages of discussing and since @GameRanma has an Adeptus Custode army I would concede overall Supreme Imperial Command to him. Ideally it would be a 4 Chaos gods and @HeiYu13's Tyranids vs the Imperial Forces I am leaning towards my Adepta Sororitas but I could run Grey Knights which would be great with all Chaos on the table.
