Prey might not be the prettiest game, but it's among the most atmospheric. Arkane Studios has proven itself time and time again to be comprised of world-class world builders. Prey is no different. If you're a fan of Dead Space, Deus Ex, or Bioshock, you simply have to buy this game.
If you're a fan of strategic management games, you have to give Planetbase a look. It's very good value for money. And who knows? Maybe you will enjoy the added challenge missions they throw in more than I did. Either way, Planetbase is well worth your attention.
I would've liked to have seen a little more story content, even if it was just some additional lore, but that's a personal gripe. Most players will probably be too busy relishing the bloody carnage the Necromancer can bring, which is considerable. This is a great addition to Diablo III, one I highly recommend to fans of all of Diablo's existing classes.
