Really like zombie survival games but tired of so many of them being shooters?
Project Zomboid might be right up your alley.  An isometric RPG set in the zombie apocalypse.  Build defenses, search for food, fight zombies.  Decidedly hardcore (they maintain that you WILL die eventually, there is no “winning” or happily ever after), this game of shambling undead is one I’ll be keeping an eye on, which shouldn’t be too hard considering they’ve got the game blog plus three developer blogs and a forum.
With any luck the game will support some form of multiplayer, which might end up making it the game I’ve always wanted to play.
This has the potential to be awesome.
