Core gameplay loop is something most of us take for granted in games and do not even recognize its existence, but the truth is that this requires a lot of planning from game developers. Gameplay loop is the “flow” of the game. What this means is all the actions you take in the game as a player, in The Forgotten Guardians case this is defined simply by player building towers, starting a new level and defeating waves of enemies. This is the core gameplay loop over-simplified, there are other aspects to it as well, but we are not going to talk about those in this post.
