i love all this gta 5 is dead stuff..and still millions of people play it..
THIS... GTA 4 online was very bad, and you had nothing to do but just do useless sh*t on Free roam, on GTA V you can do missions and such with friends and people on the server. That's a huge step foward. You can't compare a first take on the console that was GTA IV with a game that's made by a company who's already experienced with the machine they're working with.
You could do co-op missions on GTA 4, bomb the base, dealbreaker, hangmans noose etc, Free roam was actually free roam.
More content does not = better game
Lastly, are you retarded? More experience doesn't mean they will improve their games, Look at the early Call of Duty games, and how much the games have gone downhill, same can be said for many other game series, which now includes GTA online
