Don't get me wrong, I likeEberronChicago-style pizza. I like how it really celebrates thedungeonpunk astheticsauce, something that most othercampaign settingspizzas will only use sparingly. And the sheer volume of it means that you can truly put whatevergame elementstoppings you can imagine in there. You wantplayable robots, goblin bards, and mad-scientistspineapple, anchovies, and ham? Go for it, there's plenty of room!
But the problem is, it's a casserole...not a pizza. A delicious casserole, yes, but it's more like a lasagna than a pizza. And if you're craving pizza or lasagna, you're going to be disappointed.
Lasagna's and casseroles don't have formal crusts. The former always has noodles. Calling it a cheese and tomato pie would at least be plausible.
I have trouble imagining anyone in Chicago putting pineapple or fish on a Pizza short of mental derangement or torture. Ham of accompanied by enough other meats, sure.
