Should I Get GTA IV Complete?

You can find complete GTA series for $10 on Holiday sales. It's worth that price.

If you don't plan on playing GTA V and you haven't already played IV then it's worth it.

GTA IV is a great game. TLAD also adds improvements (like you don't fly off your motorcycle as fast when you hit something)

And TBOGT is the one of the best and most fun GTAs I have ever played.

Definitely grab it. Fantastic pack.

Absolutely yes, I am playing The Ballad of Gay Tony right now, and finished both GTA IV and The Lost & The Damned, its one good story combined and connected together in 3 parts, definitely worth getting with or without sale.
