1. You Overcooked It
This is probably the No. 1 reason your game meat tastes gamey. Normally rational humans who would never think to order an expensive rib-eye in a steakhouse anywhere past medium-rare (okay, medium), turn their precious butterflied backstrap steaks into charred, gray wafers then complain about them being tough and livery. Let me tell you, again, what any good game cook knows, whether he's grilling venison steaks or roasting a whole duck: Don't cook it past medium-rare. It won't kill you. I promise. And you'll discover that game meat doesn't taste gamey at all.
