Yah I realized I wasn't going to toutch that unless I spend more time than I'm currently willing learning BAR.
I just went through economy tutorials, and BP is so messy in BAR. Holy crap.
One thing I am not sure on that seems absolutely crazy about BAR is that everything needs metal, some things need energy (not to spend metal, but the building has an actual energy cost) which is fine, and build power... which is really time units if you think about it.
So if I have a building that costs 100 metal and 100 BP, and I build it with a 10 BP con, I spend 10 metal per second for 10 seconds. Ok, same as ZK.
But if I have a building that costs 1 000 000 metal, 100 BP and I build it with a 10 BP con, that same con now spends 100 000 metal per second for 10 seconds? Do I get this right? If so, how do you explain to new players that this con with 10 BP sometimes spends 10 metal per second, sometimes 100 000?
This is of course an extreme example that doesn't exist in the game AFAIK, but if I understood the tutorial, that's how it would go.
People already struggle with 1 BP = 1 M/S, and BAR wants different projects with different ratios? Brrrooooooooooo...
