Tips to make game more interesting

I have played CK2 for almost 150 hours + demo for around 50 hours. Any advice to make game more interesting? At the moment it feels like if i start anything above count i will blob too easily. Have been playing on hard difficulty + not save scumming but still blobbing is pretty easy.

So basically any interesting characters i hould play as, or mods or rules or anything to spice up the game.

Have LoR and TOG expansions.
