RDR Undead Nightmare add-on or full-game

[matt]

I just saw on the PSN Store that the RDR Undead Nightmare is on special on the January Sale for R85.50 (R95 for non PSN+)

There are two options, 1: Undead Nightmare Collection (add-on), and 2: RDR: Undead Nightmare (Full Game), they are both the same price.

Here's what I'm wondering.
1. I have RDR as a free PSN+ game, so will the add-on work, or must it be the full disk game?
2. If I get the standalone version, does it carry through my stuff from the RDR game, and if not, does it carry through my stuff if I get the add-on version?

Really, I'm wondering what version is better to get....

Opinions?

If you already have RDR I dont see a problem with the add on working whether its on disk or HD, free or payed for because Undead Nightmare is not directly linked to your RDR game, its basically its own game with the same characters. Even has its own multiplayer section.
If you buy Undead Nightmare in the shops the original is not required just like the GTA IV add ons.
