You finished the gta 5 campaign in 10h? You just speedran it once?
If not, nice hyperbole...
(rdr2 campaign was also more than 10h, to name a recentish Rockstar game) . Many other big AAA titles aside from cod also have campaigns that last longer than 10h.
I think the point is - it's disappointing to see GTA 5 2.0. I expected something more, something different, less generic, not just another coastal city or a GTA 5 clone. It seems like they just merged the engine update with GTA 5. Watching the trailer bored me, like being forced to watch a mediocre action comedy movie. I don't know how the majority of the game will feel, but this trailer is just so generic. If this were a movie, no one would care. Maybe that's the point, but still, my hype is somewhat gone. I at least expected a different scenario than this GTA 5 DLC story or at least set it somewhere other than a coastal city.
