I used to play civ5 on Immortal and the game still bored the hell out of me. It didn't bore me for ease of difficulty (it was actually a challenge for me); the game was just damn boring.
I've moved on to EU3 and am loving every single moment of it. It has way more immersion and long-term decision making than civ5, and perhaps any civ game.
