cross play would absolutely kill console markets.
PC has mods / bots / and pc has an endless issue with players making 30+ accounts on a single pc.
To multibox on consoles you actually must have multiple consoles and multiple controllers, which isn't the case for pc.
PC has dupes that are exploited to an extreme degree, plus a marketplace rediculously inflated due to said dupes / botters / ease of gameplay with mods.
If crossplay was added between the consoles then that wouldnt be so bad. But with how trove is currently, pc players would completely overtake and control all of the economy if pc was mixed with the consoles.
