>>713637579 (OP)Eh, people had hopes for future games
>old heads move on>leaders/new talent focused on other stuffIIRC Naughty Dog tried to conceptualize a new Jak game but their artists especially were more geared towards realism by then
So instead of trying to push the series in that direction and get a quick cashgrab they left it well enough alone
Sly is likely much the same way and as for Insomniac, well, they kept making games but even with the right talent devs sometimes want to try new things for a while
