If one nation gets left alone until turn 60 while everyone expends resources fighting, they will be way ahead anyway.

No way. If you've gone 60 turns without attacking anyone, you're most likely irrelevant. You're going to lose to the two or three other nations that have been taking all the land and are three times as large as you are. Unless you're playing with newbies or on a HUGE map, or some other strange setting.
