I have a feeling all those making fun of the OP are players who never played on PS3/360 and joined the community on PS4/XB1/PC so they don't know how the game used to be and how much fun it actually way prior to all this futuristic crap.
Before if someone wanted to kill you they actually had to drive across the map and chase you down, Now they can blow you up with a single click, send a strike team or simply fly across the map on the oppressor which to me isn't in the true spirit of the game.
Players who joined post PS4/XB1 will never know what it was like to have to EARN our weapons by ranking up instead of having all but a few weapons unlocked at level one or having to rob all the stores on the map just to earn enough money to buy their first two car garage or play Rooftop Rumble for hours on end to finally afford a decent car but the payouts were decent enough to where it didn't take long and the most expensive car was $1,000,000 but all of it was fun to do now it's a chore as everything is so expensive and the chances of owning them all doing legit work is very unlikely without buying shark cards.
It seems that many of them were playing GTA on ps1/ps2 or pc. "Realistic" seems to be the main point of contention. It has never been, really. This game has always been rooted in freedom and chaos packaged in absurd, childish humor. Anybody upset about online ruining the series identity never played GTA 2. As for all the flying Deluxo' s, Batmobile's, and KITT's, I think alot of that stems from the PC community's successful mods in GTA IV, like the time traveling Deloreon, the many Batmobile's, and KITT. Not to mention the many military vehicles. Also, Rockstars clear affinity for tv/movie parody, has been demonstrated by every GTA game ever being loaded with parody and references. IDK, I think OP must have been seeing those games in a Jack Thompson light. It's rated M for Mature because you have to be mature to get the joke. 30 "Claude Speed's" in one city will always turn into Liberty City Survivor without restriction, and THAT would be the wrong direction in GTA. Anything preventing me from going on a "rampage" or creating a "State of Emergency" is fundamentally non-GTA.
