Doesn't mobile have the larger install base and undercut equivalent console offerings by a ton?
They're already charging more for smaller install bases.
Not saying they're milking instead of recouping costs, but costs do scale inveresely from consumer base size pretty consistently. Mobile is cheaper than PC is cheaper than console.
That's because mobile ventures won't sell unless they're dirt cheap thanks to the race to the bottom on that platform. It's a very different ecosystem and devs make allowances for that. The cost versus profit structure on there is much different than in the other spaces. That's a market where many of the baseline products are completely free, which isn't a tactic the others embrace, because of differences in the ecosystem, volume of the market, and willingness of the consumer. Also, it's entirely digital.
PC is also cheaper, if it is cheaper, because there are rarely manufacturing costs. That market is also almost completely digital, which cuts out much of the production expenses. The main reason given for these upticks in price are non-existent (or very uncommon) for these cheaper markets, do you suspect there might be a correlation?
The barometer to measure equivalency is best for other actual consoles, whereby the parallels of structure and production is the closest.
