Has a fascinating gameplay, but it isn't a standard Paradox global strategy. It's still global strategy in medieval Europe with one issue for me. It's damn SIMS for players over 30 with murdering and royal intrigues. Despite that all issues game is still playable. You still can spread your religion or conquer for throne of Byzantine Empire, so I recommend ckIII to play at least 2 hours.
UPD: I'm cooked with the new starting date
