GTA Advance is not known by many GTA fans, because it was released on GameBoy Advance right when Playstation, Xbox and PC had taken over the video game world.
It's a 2d top-down game like GTA 1, GTA London 1969 & 1961 and GTA 2, but it's story is set in the 3D universe (that's why you see a lot of characters from GTA III and LCS).
Before the game starts, you see something that resembles an intro for like a minute, yeah, you literally see just text about the game developers for a minute without anything else from the game, other GTA games had intros where they show some footage from the game while the game's developers, producers animators etc are shown, but not in this one, all you see is just some text and some things that look like butterflies which have nothing to do with the game.
The game has a good cutscene system for a 2D GTA game, in GTA 1 and GTA2, all you could see in phone missions was just 1 or 2 sentences.
The driving sucks, the handling isn't bad, but it's very easy to crash, in other 2D GTA games, the camera zooms out depending on how fast you're going so you can see what's in front of you and avoid crashing, but in this one, it only zooms out very little so when you're driving towards the right (no matter which side of the road you're on) you will crash into a car that you didn't see because it was too in front of the camera, another bad thing is the crash physics, in other GTA games if you hit the side of a car, it will probably bounce away out of your way, but in this game, no matter which side of the car you hit, it will just bounce like 1 centimeter away, and you'll have to keep crashing into it to get it out of your way.
Now about the weapons, the weapons are the worst thing in this game, have you ever played a GTA game where killing someone with bullets takes longer than beating them to death? The bat is very annoying, if 3 or 4 guys are attacking you (with punchs) and you're swinging your bat at them, they won't get stunned, they will keep hitting you and the bat does a 90 degrees turn in front of you and the bat won't do damage to an enemy even if it hits him, it's impossible to know if you're hitting them, but in the end, you'll always be the one to die. The only gun i managed to kill people with is the shotgun, but even that was sh*tty, the enemies always seem to walk towards you so when you fire the gun while they're right at your face, the bullet will penetrate through them and miss, and you can't punch with a weapon to kill someone that's right on your face, you have to get back a little and shoot them with the gun.
The movement also sucks, in GTA 2, when you press Left or Right (on the D-pad), it will make you spin and you can spin as much as you want (360 degrees) so you'll be able to shoot wherever you want, but in this game, you can only face up, down, left right, or rear, if an enemy is 60 degrees towards you, you're f*cked, you can only face 45 or 90 degrees so you'll have to get closer to them to kill them with your gun.
This is why GTA Advance is the sh*ttiest GTA game ever made.
