### Game Concept Preference  
Regarding the game concept preference (RQ1), participants preferred the _Anottalon_ game. This rejected our hypothesis that _Tesoros_ would be the preferred game. The high level of Interest/Enjoyment shows that this construct was a factor in the selection of this game. The finding is supported by the players' comments (Their comments are in Spanish, but translations are ours) on why they would play this game again. One participant argued that '\(\cdots\) is more enjoyable, the concept is the same, but the part before the classification of the word makes it less tedious and more interactive (\(\cdots\) es mas divertido, el concepto es el mismo pero la parte previa a la clasificacion de la palabra lo hace menos tedioso y mas interactivo), P2476 (A unique code is used to identify research participants and keep them anonymous)'. Another factor in choosing _Anottalon_ as a game to replay in the future was the high level of perceived competence. This is confirmed by the comments of participants, such as '\(\cdots\)1 felt challenged while playing by avoiding the obstacles, it motivated me to play again. (\(\cdots\) me senti retado mientras jugaba al esquivar los obstaculos, me motivaha a jugar de nuovo. ), P1103'. The second most preferred game was _Tesoros_, which also showed a high value of perceived Competence. This is corroborated by the qualitative results, which demonstrated that _Tesoros_ was the game that provided a feeling of achievement for various participants. For example, one participant mentioned the following: _'perform perfect rounds and win jumps (Hacer rondas perfectas, y ganar salos), P3957'_; another commented _'try to solve everything correctly to gain lives and coins, and thus position myself in the top 5 (intentent resolver todo de manera correcta para ganar vidas y monedas, y ast posicionarne en el top 5), P4162'_. That _Tesoros_ came in second could be explained by the fact that five implemented GDEs (i.e., adaptation, challenges, levels, rewards, and theme) were found related to the enjoyment in this game. The previous fact was corroborated by the participants' comments, such as _'it is more enjoyable because there is a goal: to collect gold (es mds divertido, porque hay un objetivo: coletar oro), P350'_. Finally, although _Agentes_ did not get rated as an enjoyable game, the study offered some interesting results on it. One of these relates to the text and phrases presented in the game: participants pointed out that they liked to see a variety of words and sentences. To illustrate this with concrete comments, _'I liked discovering the words that are used\(\cdots\) (Me gusto descubrir las palabras que se usan\(\cdots\) ), P3772'_ and _'the infinite sentences that it shows, haha they \begin{table}
