My first time logging in and walking through Gridania, I remember seeing a male Roe in a giant moogle mask and leopard-print Speedos doing the Manderville on top of a lamp post that had no business holding his weight. Immersion breaks when people are given the freedom to break it; the only way to prevent it is excessive railroading, which is even worse.

As for Solution 9, while I won't judge it in full until I actually get to play it myself, so far it doesn't really feel out of place in a setting where we stumble across ancient ruins filled to the brim with forgotten magitek and bio-engineered horrors every time we sneeze.
