GTA 4 alone?

yes the storylines does not follow the previous installments

It also has little tutorial missions at the start to help you learn

free aim

Fighting

Chasing

so it dont matter if this is your first GTA.

dont worry its definately worth the money.

it took me a month to complete the storyline

maybe cause i didnt rush. their is so much you can do instead of just the main storyline

enjoy the game

GTA4 has no connection with the other series at all, but if you play any of the other GTA series, you might want to play 3, Vice City, and San Andreas, you might find you like them better due to things like vehicle control(Vice City has loose controls while San Andreas has very locked and heavy controls), graphics, planes(Only San Andreas has air planes, GTA4 only has the chopper), plot line even, and a lot of other things.

So yeah, GTA4 doesn't have everything in the previous games, but you should try it if you want.

No, this one is totally different. Not connected in any way to other GTA's, except that it's in the same city as one of the other titles.

But no, there is no storyline connection in any of the GTA's.

you dont have to play preveious games for gta it has aseperate story and it tellsyou the controls

you can play it. each GTA has a different story line.

You'll learn it pretty quickly. Buy it, it's amazing.
