I've always wanted to see 'epic' types of bad guys, you know, the bad guys that are so damned powerful that they can wipe your whole technologically advanced army out in a single shot? I'm not talking about epic factions, but rather..
- Epic bosses that protect places such as the Lost Library, and other ancient ruins.
- Epic bosses that roam the land once triggered, and they ravage the country side.
- Epic bosses that roam the land which are randomly generated, and perhaps they can found their own city.
They could have a random name generator specifically for this, that make the names of these bosses sound 'epic' as well. Such as..
Kelvar the Invincible
Amon the Supreme
Perhaps upon killing them, you may get some 'epic loot', such as "Kelvar's Plate Armor" or "Amon's Staff of Power". Or, perhaps the ability to use the resource, if they are guarding it.
