Years ago playing with a certain GM, all the players had to learn to min/max due to the GMs anti-PC outlook.
He didn't allow potentials, so stats were lower. You had to pay DPs to increase stats, a lot of DPs too. He never gave any extra DPs but mandated you had to have the right skill. We did use RM2 and all those skills. Oh, and no similar skill either. You had the exact right skill or you didn't.
Then his NPCs were powerful. But when we got a hand on their items, he'd have a magic eating monster come and now your x2 PP is gone, or whatever stupid stuff.
Looking back at it now, he really wasn't a good GM. I remember trying to buy items, when asking "How much for this +5 magic shortsword that you have 10 of in stock" the response was always "How much you got?" Couldn't stand that the price was dependent on how much I had, ofcourse that as GM he knew but the vendor never did.
