I normally take out my development frustrations on tanks and SAMs in DCS A-10 and Su-25T, Migs in FC3, or a session in the good ole Worms 3D. Command & Conquer 3 Tiberium Wars is another option (only on really bad days)...I usually totally wipe the floor with Scrin and Nod forces (Love doing so with the GDI Mammoth).....
