Oh~! I love tower defense(TD) games. This is my favourite browers games genre and I am going to share my thoughts about TD games in this article.
The goal in a TD game is to build defending towers to stop or eliminate the incoming waves of enemies to reach the end point of the given game board. The fun of TD is about resource allocation, decision making about the timing and positions of placement of towers, so TD is a subgenre of real-time strategy(RTS) games. It is undeniable and not surprising to know that RTS games are the precursor TD because the scenarios of using stationary towers to defend enemy mobile units are prevalent in RTS games.
