I have to say Novigrad too

It's huge, feels like an actual city and it's just so cool to wander around in. You could almost have an entire game just in Novigrad

New Mombasa at night is :ok:

I liked flying over Gracemeria in the CFA-44 in Ace combat 6. Good times.

Paradise City
Hyrule Castle Town, OOT
Whiterun
Bayview
Imperial City
Liberty City
New York, Spiderman 2
Los Santos
Goldenrod City
Viridian City

Los Santos from GTA 5. Rockstar did such a fantastic job at making Los Santos almost completely identical to Los Angeles. When driving into the city from the freeway in the game, it really does look the same as it does in real life. Some of the places in Los Santos I have actually been to in real life and that feeling is really cool.

Bayview in NFS: Underground 2 is one of my favorite cities. The city is like Los Angeles, San Francisco, and San Diego combined and there's tons of different places to drive whether its the busy downtown streets to the curvy roads in the mountains. This game still looks pretty good too. It aged really well for a game made in 2004.

I love Diamond City in Fallout 4 mainly because its the remains of Fenway Park and I'm a huge baseball fan. Telling the guy that sells his custom-made swatters what baseball really was is always a good laugh. The residents there also worship the Green Monster (big green wall) in left field which today is one of the things that makes Fenway Park famous. I also love how Bethesda kept the red chair in the right-field bleachers where Ted Williams hit the farthest baseball ever hit in Fenway.

Las Venturas is another city I really like and Las Vegas is a city I want to visit so bad and see the similarities. Driving through the strip at night in Las Venturas really is atmospheric, seeing all the nice cars, the lights from the casinos, and Elvis-looking NPCs walking around is really cool. I really want Rockstar to give Las Venturas another shot in a future GTA game or perhaps some sort of singleplayer DLC for GTA 5.

Haven City in Jak II

My second choice tbh

I always preferred the quiet nature of Haven City in Jak II compared to the war-torn streets of Jak 3.

-Bayview from NFS: Underground 2 (thanks Jono)
-Mossdeep City from Pokemon R/S/E (idk, just liked the place although the Gym leaders invariably gave me a pretty hard time)
