I try to use these resources as realistically as possible too.
Cheating(or someone taking advantage of game flaws)is a problem I have alway's run into in the past when playing PBEM or H2H games,especially on ladders. That takes any enjoyment right out of it. I haven't played any PBEM games with the SP series yet. From the sound of it I'm not sure if I ever will.

An agreement with a
regular PBEM opponent is the only way I ever got a "fair" game.

Just my 2 cent's worth.
