All the Grand Theft Auto games were created by the Rockstar games company (you can find their profile on Wikipedia).
no, just tbogt.
no, but nice try.
You can only get a parachute in TBOGT, there aren't available for GTA IV.
Purely personal choice, but I like Electro Choc.
you cannot use nitrous in the normal gta 4, but you can on TBoGT in a race
the akuma or Vader takes the show when it come down to that.
what? if your talking about the dlcs compared to the main, they should be clearly labled differently. only a fool could confuse gta4 disc with tlad and tbogt. :P
I tried the boats in TBOGT, including a police launch, but I haven't found an armed one yet. You can do a drive by on any of the boats though, using the SMG.
Only in the DLC GTA4: TBoGT (The ballad of Gay Tony). It is called an 'APC' and is a NOoSE (National office of security enforcement, similar to homeland security) Tank and there is a Cheat code for it.
Maisonette 9 is open from 2100 hrs to 0600 hrs - 7 nights a week.
some in tlad are passed down to tbogt, but the answer is sadly, no.
use gta4.net to locate it. its around the left side of starjunction, but the next street, not starjunction.
