I've played a good amount of Star Wars Galactic Defense, and despite it's obvious flaws, I've had fun. I keep hearing that it's a complete ripoff of Kingdom Rush, so I'm planning to play both of those games soon. One thing that Galactic Defense has taught me is that I really am enjoying that style of tower defense. I've never been a huge TD fan, but it seems like I enjoy the Kingdom Rush style game. Therefore, I'm curious what are some other TD games that are recommended that are similar to Kingdom Rush/Frontiers?
