I'm trying to figure out what the cost should be for a simrig with a hot sim module. I had three main ideas. First, maybe it's just not possible. Second, it costs 2.5 times a cold simrig (just like a hot sim module costs 2.5 times as much as cold). Third, you just add the difference in cost of the two sim modules.
I personally prefer the last method. That raises the price of an external simrig from 1,000¥ to 1,150¥, and an internal one from 5,000¥ to 8,000¥. The second method raises the prices to 2,500¥ and 12,500¥, which seems excessive to me.
