I'm kinda in the same boat on the wait and see. I set back $10 for the DLC last week, but now that it's out I'm hesitating. I was mainly going to get it so I'd have all the RDR DLC's so I didn't have to worry about going into match making and not find a game because everyone was using DLC I didn't have. On the other hand while the other DLC sound awesome (online poker, zombies, and so on), this one doesn't really have anything I want. Tomahawks sound too similar to throwing knives, and the Legends I don't really care about, so in the end it'll boil down to the word of mouth on how fun the map packs are.
It also doesn't help that even tho I don't read it, the Scott Pilgrim demo was very fun, and $10 too, it reminded me of the old Simpson's arcade but with more features. Then I saw the $10 Capcom PSP Arcade game, and well...let's just say I'm conflicted lol. I mean it's not like $10 is an insane amount to spend or anything, but the RDR DLC is getting some serious competition this week lol.
(I mentioned the PSP game because my PS3 is finally dying on me. I backed up my info, went thru the PS3 safe mode options, and when that didn't work I tried reformating and everything was still bad with texture problems and frame rate and sound stutter, so sending it in for repairs. So want to load my PSP with some PS1 classics and such to keep me busy. Will say tho that everyones right, the Sony help service is a very smooth and helpful group.)
