Oh please, is a arena shooter, no way that can cost 400m.
-8 years of production+development
-high production value that matches other products made by studios under sony (we already know that games like horizon zero dawn and last of us 2 had a budget over 200kk)
-one of the features promised was weekly short-movies about the lore and characters
-also they promised at least
3 seasons of content for the game
I can see it costing over 400kk mainly because its a live service game with playstation tier production value.
Not only they had to waste money on their shiny graphical fidelity bullshit (which is expensive as fuck), they had to work to pump content (with the same bloated high fidelity quality) for upcoming seasons and the weekly shorts bullshit.
Playstation games are bloated "muh graphics" movie games, Concord added live service shit (and animations and weekly shorts) to the mix. Bloating their recipe that is already bloated.
