To expand on this point, in my experience regardless of the wargame model/mechanics one uses, once you've corrected for biases and assumptions the results will start looking closer to each other and to the real life outcomes. It's also why even games with seemingly inaccurate equipment models such as War Thunder can more accurately mirror real life combat dynamics than something with supposedly more accurate vehicle models like DCS World.
Use logic, doesn't take too long to realize the for the US fighting a protracted war against a country of
1.6 million km2, with land borders and that can built its own arsenal from two boats and far off bases was an horrible idea. You don't need a simulation, you just need a map.
China is a massive country with land borders, a lot these countries in the pacific are islands very substible to trade disruptions and doesn't take that much, attacking a few shipping vessels and the entire shipping industry in the region collapse, nobody is going to take risks in a warzone, that would mean
the total economic collapse of the pacific region. And that is not even counting that these countries economies depend on trading with China, there is not other way around it.
I think a lot of the countries are going to impose pressure to avoid or even fight against blockade or trade disruption that could harm their economies. A lot of these countries with the exception of a few know the US not from the region and they can go from the region if become a stalemate, these are countries are the ones who are going to be left dealing with China alone.
From tactical standpoint these "chokepoints" are not very defensible at all and they are really susceptible to saturations attack and ballistic anti-ship missiles, that would depleted the defenses of the vessels and countries defense who defense budgets to be honest are not as high as US or other military powers.
Is complicated and a situation that many countries in the region would rather no be in, I dont think a Island at 100 km of the coast of China it worth the mess.
