a 25 hour gta 6 story would be better than a 60 hour one

A huge map does not require a huge campaign. I would rather finish a sharp 25-hour story and spend another hundred hours exploring than watch the main plot pause for fifteen missions that exist because the budget was enormous. Long games often confuse duration with importance. Every character needs a subplot, every system needs a tutorial mission and every region needs a reason to appear in the campaign. The result can feel comprehensive and still lose momentum. Give Lucia and Jason a focused story with room to breathe. Let the open world carry the scale. Credits appearing before exhaustion would be a feature.
