I believe the newest game brought into the state of Minnesota is Halo2. I haven't tried it yet but I will venture it is initially challenging.
As for huntable game, turkeys is the newest I'm aware of though they have been around for over 30 years. Elk numbers are building, mostly wanderers from Manitoba as our "remnant" herd is managed at roughly 35 animals to keep farmers happy. Woodland caribou are becoming frequent visitors as the Boundary Waters and Superior Forest age. I've seen them once and I've been told it is becoming a more frequent occurance. Mountain lions seem to be making inroads here too, the DNR at least doesn't insist they are not residents in the state, just not a viable breeding population.
