Hey a friend told me about a very ambitious game called No Mans Sky. He said the planets and ecosystems for the planets form as you travel and the game is crazy huge and it has endless game play. Its also supposed to be multiplayer so I had to check it out. He was right. This game looks really roamtastic and will definately itch a scratch that many gamers have been waiting for. I have played a lot of mmo's and havn't seen many like this one(Mass Effect style?). It has a lot of great elements that mmo gamers love, especially the freedom to do whatever you want in a huge universe - in a space ship that shoots lasers and a universe unique every day. Here's a review with a couple videos:

It has an exclusive with PS3 but is to be released on PC as well: http://www.polygon.com/2014/8/1/5960215/no-mans-sky-pc-ps4-timed-exclusive

This game was shown at E3 and got some really good responses. I think it will be one i'll have to check out.
