There's the event chance mod, which yes lets you fight endless small waves of random enemies. There's monster mash, adding a few challenging enemies. I even want to shout out friendlies reloaded, it's lovely having some lads defend your kingdom.
I didn't build a massive castle and walled in village with a 5000 wheat wheatfield just because it's pretty.
Give me a mod that allows the user to customize events. Wave attacks that aren't incredibly easy. Mix and match enemies.
6 trolls, 20 skeletons, 5 draugrs, 20 grey dwarfs, 3 fire bois, and maybe 2 fulings.
See? That's an event. I want to watch my village burn. I want hundreds of skeletons mixed with greydwarves. I want overwhelming despair as the corpses pile up.
So yea. Let me know if anyone's taking requests…
