Leon's campaign was the only noteworthy thing about about RE 6. The rest was poo. The AI partners would leave constantly leave you waiting, when you're ready to go into another area, and there are so many times they'll just ignore your commands.
Plus, how many forms did Simmons have again, after he turned into a Werewolf horse-thing. So much for atmosphere .
Once you get to the Church with Leon, his campaign turned to ****.
