I thought GTA V had the most well-realized open world ever created. Exploring was an absolute joy for me.
Yeah me too. But I think he means more content with game-play modes or systems. I mean, I've been playing GTA V non-stop almost a year now, and I'm still finding new details, finding new nooks and crannies with surprising detail... finding new buildings that are surprisingly unique and based off of real life examples... or just finding new places to have police chases or gang shootouts.
While not every example is good, this thread and in particular these two pages really show off the 100+ days that Rockstar said they spent taking photographs of LA to base LS on. Even to someone that's played the game many times now, I'm pretty impressed and even surprised still just how many buildings are unique in the game. The game is, at least when you're in that sort of no-gameplay-needed relaxing mood, such a joy to explore.

I think these two pages of the photography thread show that off, too, but instead of showing the quality of realism (whether the buildings are actually realistic to real world architecture), show the quality of just artistic design. There are just so many areas that feel like little hand-painted dioramas.

I do wish there was more content to do there sometimes. But sometimes just exploring these areas is enough. I've beat the game 8 times now so obviously the combination of story and art must be good enough to keep me coming back.
But I'd definitely be up for some new property missions, more properties, more garages or safehouses, maybe even upgrade-able properties, maybe repeatable missions like photography missions, trucking missions, fishing to compliment the hunting, and of course planning heists (or even just holding up a la gas stations) those empty Fleece banks all over the map or adding heistable interiors to more office space (imagine doing heist 'runs' on various company HQs a la Shadowrun on Genesis with the Tangerine Dream soundtrack). Just, more stuff to do.
