FPS is now finally starting to get traction in Western markets.
For me, the most interesting games in this category include: 1. Pixel Gun 3D, 2. Zombie Frontier 3, and 3. Critical Ops.
My feeling is that this category is starting to get real for Western markets. Was super impressed by Mad Finger with Dead Trigger 2 but they have largely been quiet since then. Their game/market to lose.
