for this year its not so much "burn out" as lack of great games so far. I can only replay my favorite games so much DMC4/Dark Souls/Demon Souls/Batmans/Disgaea/Valkyrie Profile. Havent seen a great game for months now although I am somewhat enjoying Styx Master of Shadows, Alien Isolation and Divinity: Original Sin but cannot get into any of these games enough to finish them yet.
Bound by Flame, Castlevania: LoS 2, Evil Within, Borderlands TPS, Tales of Xilia 2, Murdered Soul Suspect, Sniper Elite 3, Lightning Returns, Watch Dogs, Drakengard 3, Natural Doctorine, Dark Souls 2, Sacred 3,Thief, Tropico 5, Wasteland 2 all were disappointing to me this year.
Wolfenstein was a nice surprise for its quality but I am very border of FPS in general so meh.
The Banner Saga was a nice surprise really enjoyed it but it was over too quickly. Child of Light was awesome.
So yah this year doesnt offer much in terms of great games imo.
