Zeke GREAT points, most I had thought of some I had not (and I have been thinking about this for a looong time)!
NO size limit, females count for sure. Time limit also a big no, this will take a looong time to accomplish the way I inted (blue collar working guy slowly saving and doing a hunt every other year or so). Draw tags vs OTC vs. private - great point. After a lot of debate all count. For some species drawing a tag is required.
I will always believe that drawing a great rifle LE tag and taking a 330 bull is no where near the accomplishment of a 290 OTC bull (most times). However all would be open as long as they were diy. I know guys draw in Utah (for example) and have 10 guys there helping them. Not the same at the guy from Vermont who drives out alone and hits it hard having neer even been in the state before - but all will count. The Utah guy may travel East to hunt whitetails or to AK for bou - new to him.
Here is my current list, still needs a little tweaking:
1. Whitetail deer 2. Blacktail deer 3. Mule deer 4. ONE of: Sheep(any species)/mountain goat/barbary/ibex/oryx/bison/muskox/mountain lion 5. Caribou 6. Elk 7. Moose 8. Antelope 9. Bear 10. What hear? Turkey? Javelina? Hogs? Wolf? Gator? Anyone one of these
No doubt guys would cheat, get macho attitudes etc, this can and will happen/ My idea is geared towards a goal for the DIY guy and a "target" to shoot for and a way to see how others have faired.
I curerntly have friend who lived in Ohio until recently that has all above except with stickbow - GREAT hunter!
A favorite book of mine is "The versatile trophy hunter" I met the author in Walmart in WY a few years ago. The books is great but I really really like the title. Many guys do great every year on elk, or mule deer (or both) by hunting the same species/area each year (like I do with whitetails). Doing good at this every year is usually just some scouting and repeating what you have done in past years. Going to a whole new state you have never seen, learning a whole new set of reg's, hunting an entirely new type of terrain and an entirely new species - ever year, and being successful is a completely different ballgame IMO.
I know a local guy in Ohio who no one knows, I have known him around 10 years and he has drawn about 5-6 good elk tags out west (not the best but good). He is around 60 and he has filled every tag with 330-360 bulls, DIY, with bow. IMO he is one of the best elk hunters there is. Almost every time was a new area he has never been in.
