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.
Here in Arkansas.... Elk.... permit hunting for only 6 years or so. Quail numbers are very low, but coming back... not by introduction, but by pen raising and management. I know some private clubs are bringing pheasant in, but I think it's going to be pretty tough to re-introduce them here.... but that or some other larger bird would be nice to have.
We're getting some Elk here now. They're mainly in the SW tip of VA. I believe they're wandering in from Kentucky or Tennesee. We've had some recent sighting of Mountain Lions but our Dept Of Game assures everyone that there are none around here. They'd never admit it but the belief of some of us is that they know all about them. We figure that they are releasing them for deer control and if they went public with it,John Q Citizen would go slap off. Of course it's against the law to shoot one here,so you can't shoot one and hand it to em saying"here's one of those cats that you told us doesn't exist" with out get a pair of matching braclets and a cell mate that keeps mumbling something about someone's little puppy...
