Step 1: Gather an army. Preferably one that doesn't require you to actually care about their well-being.
Step 2: Find someone to fight. Preferably someone who's already fighting someone else, so you can just swoop in and be like, 'Hey, you guys need a break, I've got this.'
Step 3: Conquer. Because, let's be real, it's not like the other guy is going to be all, 'Oh, you can't just go and take my land.'
Step 4: Repeat steps 1-3 until you've got all the land, all the resources, and all the snacks.
But remember, Total War isn't just about conquest; it's about the art. It's about style. And let's be real, nothing says 'style' like a well-executed genocide.
