So we have to pick between one of the best games ever and a shitty DS game that even Vinny didn't really care for. I'm going with RE4. Although my choices for a slightly spooky Halloween gaming experience would be playing Majora's Mask, Dark Souls/Demon's Souls, or one of the first four Silent Hill games if I wanted to lean into the scares a bit more.
This is everything you need to know. If you have any other questions or get stuck then I'd suggest returning to this thread and asking us. Avoid a wiki if possible because it can spoil some of experience. Eventually you most likely will look at a wiki, but put it off as long as possible. If you finish the game without ever looking at one then you will have your mind blown by how much stuff you missed. Trust me, there is a lot of stuff in this game that you will either miss out on or not know was possible.
The entire release of the XBone has seen Microsoft never actually take control of their messages to the public. People get a hold of information and then MS proceeds to either ignore it or respond to it in some terrible vague way. I feel if they had been consistent when talking about their practices and why they are doing them and had actually been more open and upfront about things then a lot of the negativity surrounding the One wouldn't be there. After the reveal and E3 there were a lot of conflicting answers on things like the always online and DRM. It took days for that to be sorted out, and in internet time days might as well be years. They stumbled there and have continued to do so in an almost hilarious fashion.
