If it wasn't for the reliability issues I had, I would still have my Ghostbusters LE. It was a fun game, and it was absolutely brutal in all the ways I wanted a game to be. That said, they REALLY need to do another code update on the game. It needs it badly.
The Walking Dead is just flat out great. It's hard not to call that game a keeper.
I didn't keep my Ghostbusters, but I'll be looking for one down the line again at some point most likely. But my honest opinion is that The Walking Dead is a more complete game and has better legs.
