Well, it was already ruined by simple virtue of being in the game in the game in the first place.
Pointless waste of time and resources when we already had the "much needed diversion" in Ep 5 with the MC humping his way through the Prep party with several HOTs. At least those were real sex scenes in terms of the them happening in the actual BaDIK world, but these DnG scenes were nothing but fantasy and took up the lion's share of scenes in this update (10 out of the 19 scenes).
With so many lingering questions, plot threads, etc, we could have had something else to move these along or address more important issues. For example, instead of this DnG game, we could have had the group of 4 (MC, Jill, Josy, Maya) leave the library together and see all those Cathy posters up on the walls which the MC decides to take down with the help of the girls. Cathy walks by and see this, then when they're all done she comes over to thank the MC and asks to speak with him in private. This could have led to her and the MC having a good heart-to-heart about the situation and the resolution with Rusty, which would then lead to a sex scene on the non-M&J path. Then afterwards he could bump into Jade which could lead to him apologising for standing her up if he agreed to meet her and possibly lead to a sex scene, but if he already had sex with her then it would be much like the scene we got in the episode.
Something like this would have been better than because at least it would actual ramifications/impact for certain relationships and plot lines, unlike the DnG game which did nothing to affect either of these.
