I own both TSPP and GB. Both great games and I don't think you would be disappointed with either one. I haven't had a chance to play TWD a whole lot, but it is also a really fun game with great code. In my opinion Ghostbusters is harder to progress through then TSPP and offers more of a challenge for me personally. GB has made me a better player due to tight shots and quick drains if you don't learn ball control.
