If you get away from Roleplaying games, you can look at Risk (the boardgame).
A board game is not an RPG, which in the OP I specifically addressed I am looking for.
1) Many already deal with the realities of real life already...do they really want to play a game with the same rules? (I mean there are some that do...but there are many that don't).
I am still looking for a fantasy RPG, not a game that deals with the realities of the players' real life.
A simple example is the concepts in the thread about what a STR 20 represents. Because 5E is
not a simulation, it doesn't do a good job of modelling what people can do IRL. We've seen numerous threads on this. Using 5E's movement rules, you would need a Speed of over 100 to run a world-recorder 100-meter sprint. Now, a 17th-level monk using Step of the Wind
could do this, but to imply all professional sprinters are tier 4 monks is ridiculous of course!
The manticore's flight speed of 50 is ridiculous. It translates (via a Dash action) into less than 12 mph. Most creatures that fly travel at two to three times that rate and can go much faster in many cases.
Finally, the English longbow with people shooting it two to even four times in 6 seconds is just plain silly. An archer using a longbow in medieval times would average closer to one shot in 6 seconds, and prolonged shooting at all would lead to muscle fatigue quickly.
I could continue to tweak 5E to make it more of a simulation of real-life and actual historical accuracy, but as I said in the OP, I am wondering if there is anything already out there...
2) The rules to actually replicate something accurately, even to a medium level would be inordinately complex. How many calculations do we really want to do to see if you are able to climb the wall 10 feet, or figure out how to open a can without a can opener, or even jog a 100 meters while jumping over rain puddles and dodging smaller puddles of water?
Not really. More complex than 5E? Certainly! But it depends on the level of accuracy in replication that determines the level of complexity. 5E has a very low level of complexity so does a poor job of accurate replication--maybe another RPG does it better? I know it will be more complex than 5E--and I am perfectly fine with that.
