Go to Rapestop and buy a used copy that has both the Lost and Damned and Ballad of Gay Tony and get lost in the last comprehensive GTA game you'll ever play in this life time.
GTA 4 started off kinda slow and clunky (The Car mechanics are horrid) with annoying characters (NIKO, LEZ GO BOWLING!) and the characters take a minute to interest you more than annoy you. Plus the selection of music/humour in that game is straight up ass and only gets better with the addition of the two DLC's that you'd have access too and if I'm not mistaken, they've been implimented into the main game once you have the content so the radio stations aren't all the way garbage.
The Lost and the Damned and Ballad of Gay Tony tell better, more interesting stories than 4 and I just loved the change of pace both offered you from Niko's campaign. Buy and eat, breh.
I already bought everything digitally...the game and the 2 DLCs
I don’t use discs...and I definitely wouldn’t buy a used 360 disc...them shyts used to scuff easily...PS3 discs never did tho...you had to straight up scratch a PS3 disc to fukk it up
