Treyarch IMO are so much better than IW and SH.
IW team behind MW1 and 2 were the best, then came Treyarch as the underdog to create the best series Black Ops including the single player that had branching narrative and multiple endings, our playable character spoke more than a few lines during actual gameplay in the campaign mode. Sledgehammer's debut solo campaign effort with Advanced Warfare is severely underrated and underappreciated imo. AW's character models, lighting, animation, set piece moments were just sublime on the new gen consoles, beyond any other COD game on a technical level. Sledge folks have immense potential if AW is any indication to go by. Infinity Ward dropped the ball big time with COD:Ghosts. Now back to Black OpsIII, the original reveal trailer felt underwhelming and I feel it was particularly to do with the choice of music, it just didn't suit the contents of the trailer. Treyarch folks have enough pedigree to pull of the Black Ops game ever with BOIII. Can't wait to see that single player campaign playthrough at E3 next month!
