For the first (An UT 10th Anniv), I really like the concept, and what one comment says. "I like the idea of Chara being your partner despite the route you choose. In the genocide ending they state how they realized the purpose of their resurrection was to help you. Maybe the ending you choose not only determines the fate of the monsters, but as well as Chara's purpose."
Actually, reminds me of Outertale (project spacetime) a bit, from the touch of lore I've heard from Red.
For the second (UT Arkangel), I think I might enjoy playing it when it's released.
