No real favorite, but I only play games I enjoy, so:
Persona 3 Portable: Dungeons are incredibly redundant, only drawing me back because the grinding is so easy and the reward (shiny new monsters) is nice and guaranteed.
Half-Life 2: Maybe I'm a bit thick, but I never really know where to go, and end up running about like a chicken with its head cut off as a helicopter showers me with bullets.
Crisis Core: Again (haha), combat is very redundant, and don't get me started about random encounters.
Mass Effect: I haven't gotten around to playing it just yet, but I'm already dreading the vehicle sections.
