Kingdom Rush is arguably the most popular tower defense game today. It was created by Iron Hide Games in 2011. It was an instant hit; it's simple, classic, gameplay style was favored by everyone who played tower defense games. However, the game is very difficult, especially to those who are not good with strategy or who are just starting out in these types of games. This game was even difficult for me, and I am very experienced in tower defense games. This game doesn't use many features that we haven't seen in other, previous tower defense games, but rather masters well-known features in a smooth gameplay while taking on the medieval theme. My only complaints are the difficulty of the game, and the simple gameplay style. It would be nice if the game was a little more unique and used some more original features, but I think that's one of the reasons of it's popularity is because of the game's charm and simplicity. This is a decent game, no doubt, however, it is very overrated.
