I played God of War III perfectly well the first time. After more than a year, I played it again and encounter a glitch that makes the game totally unplayable.
Kratos cannot latch onto the shiny lights that allow him to swing, jump over cliffs etc. The R1 button works fine, opening chests etc. but doesn't work on the shiny light. Cannot progress with the game after encountering the first shiny light in Gaia's Heart.
