Anyone ever notice that in Haven, you never see idle Strangers and knights? Don't they ever eat? Sleep? Go to the bathroom? I'd pay to implement Stranger children. Perhaps they'd run around, chasing Snipes with gleeful abandon?
Same could go for the Arcade. In those Wolver Dens, perhaps you could see some more critters in the background, lazily sunning on a rock, play-fighting, etc. For example, there could be a, say, Voltail poking a Quicksilver, prompting the latter to spazz all over the place, provoking a growl, etc.
In Deconstruction Zones, there could be metal structures in the background that periodically fall with enormous explosions, followed by a Demo yelling "Oops. Uhm."
Any other suggestions? Or feedback? Why DO they call it feedback?
"I'll feed you back."
"I never fed you in the first place."
"...This is awkward."
Robot children? :/
but +1 for more scenario rooms.
