Haven't? I've played them all(less the last couple of missions of Halo 4) & my problems with Halo wasn't just with 343. Reach by Bungie was also not that spectacular, at least for me. Yeah you were a Spartan III & they had a space mission or 2, but you didn't play as the Chief & you already knew what happened to Reach. I think going with a prequel was unimaginative & forgettable. ODST on the other hand was awesome & different. I would have preferred they done an ODST 2 instead. Halo 4 was interesting, but there was either something off about it or I was just over-saturated from playing too many Halo games. It's always good to have a break from something for awhile before getting excited again. Let's see if that happens with Halo 5. I think they learned a few lessons from Halo 4 & now Halo MCC. They can't afford to make anymore missteps.
