Some of these proposals are focused on specifying and/or constructing different parts of a language processor (e.g., [6][11]). Therefore, they are of a more advanced nature than Evaluators, which is focused on the initial stages of the learning process.
Other proposals, which are focused on visualizing and/or animating different phases and/or algorithms in language processing [3][7], lack the immersive and motivating features promoted by game-based learning. Additionally, Evaluators has a narrower and more specific learning goal: to learn the fundamentals
