"That has several implications.... one is that playing violent computer games can have beneficial effects."
I doubt this study demonstrated that the 3D game has to be violent.
Logically, 3D game which involve aiming and tracking mechanisms help raise situational awareness in ways two-dimensional puzzle games cannot--it's very likely that non-violent 3D aiming and moving games, if they existed, would also work.
