question about the lost and the damned and gay tony

Is the lost and the damned and gay tony stand alone content or do you have to have grand theft auto 4 to play them?

They're stand alone games. You don't need GTA4.

awesome, many thanks

Actually, depending if you buy the retail version (like you buy the disc at a store), it's stand alone. If you download it from Xbox Live, you'll need GTAIV.

you will need gta4 if you download those versions from XBOX LIVE
