^That may be true, but some games encourage camping more than others. I've always thought that CoD does this with killstreak rewards, the very small kill times, perks that make you invisible to the radar and certain attachments (Heartbeat, IR scope) and equipment (tactical insertion, jammer, motion sensor, camera spike, claymores), etc.
