**5.3 Discussion**

As the results show, the DAO concept can be integrated very well into games that are based on a blockchain. Thus, the application was able to achieve an SUS score of 70 points and can be considered good, as already described. The score is comparable to the Facebook app for iOS from 2018, as described in [14]. Many of the respondents stated that the collaborative decision-making approach had been the most exciting and fun aspect.

The evaluation of the free text fields shows that there is potential for improving usability in the way communication is handled within the teams. A chat could satisfy this need and make the game more fun. Likewise, assigning user names would simplify the identification of players. As a result, the SUS score can be sustainably improved after the implementation of these functions. Since the game has been implemented almost entirely in a decentralized manner, as described in Sections 3 and 4, the long waiting times after a vote has been submitted cannot be prevented or can only be prevented with difficulty. This is because the performance of the game correlates with the performance of the blockchain.

When evaluating this application, it should always be kept in mind that it is a minimum viable product (MVP) whose goal has only been to investigate the DAO concept with regard to the usability of a game.

Moreover, as described in Section 5.1, the population of respondents consisted of known individuals. Similarly, the number of respondents was so small, 42, that the representativeness of the quantitative survey could be questioned. In addition to the size of the population, the homogeneity of the group may also have played a role. As described, it consisted mostly of people who were under the age of 30 and male. All these factors could have contributed to the good SUS score. Thus, it is not possible to clearly assess whether the created application could achieve an SUS score of 70 with a different constellation of respondents.
