Finished The last achievement for the Dead Space remake. That is definitely the definitive version of that game, when it was announced I really didn't think that it needed to be remade because the original does still hold up well in my opinion. The remake is excellent though, and it doesn't feel like an old game with a new coat of paint, it feels plenty modern.
You've never played it before, don't let the price tag he grudge you because it's not a completely original game. For people that did play the heck out of the original, your mileage will vary. It's one of my favorite games in one of my favorite genres, so it didn't take much to talk me into it.
Don’t think anyone mentioned it here but there’s a punch card to get 2500 points for buying at least $40 worth of newer/upcoming games. Quite a lot of games included in the promotion. I was planning to get the RE4 Remake day one so that’ll qualify.
Sadly, I’m guessing the days of 6000 points for buying a new release are behind us.
At least if you buy it through Microsoft.com, there is cashback available, combined with rewards gift cards, it's still a decent deal for digital at launch.
