Enjoyed all of it except for Chris's last chapter.
Jake and Sherry's campaign is by far the best, so many great moments that I enjoyed. Leon's campaign was good too, just enough survival horror without completely losing the action. Leon's is thankfully similar to Revelations. Which is good. That is preferable over the archaic cliches that the older games had.
Eh some what disapointed with it really D': it was over hyped in all honesty.. now don't get me wrong it's by far better than 5 but it isn't as good as 4 was in my opinion. However I'll push further and see what happens because some games just take some time getting use to or to get into. (I felt like FF13 was terrible until I got half way through disk 2 or near disk 3 and now I love it)
