Bloodborne will be the highest rated esclusive for all 2015.

I'm guessing it'll be between that, XCX, and Persona 5. Halo 5 also has a good chance, but i'm not sure if i343 will be able to hit the standards Bungie set with 1, 2, and 3. You never know though ^^

Updates!

I'm only going to be updating the top graph/list today, but i should have all the other's done some time next week (if you ever want to know how recently something was updating you can expand the images and find a small date stamp in the top right). I'm also going to start working on the 'true' 8th gen exclusive list, now that all three have enough games for it to be a worthwhile graph. I've included some titles here that are still gaining reviews (so i don't have to later), but i'll update any changes that happen to them along with the other graphs. DQH is the only one i expect to see any major changes to though.

If you see any errors or a game missing, let me know and i'll get it fixed in the next update ^^
