I like the graphical distortion border in the cyberspace stages. It's like a mix of null space and old stages. Honestly that GHZ is how I always envisioned an alternate final stage in Generations, one where Eggman's time fuckery caused Sonic to run through a warped and distorted version of GHZ being torn apart. Oh and Rest in Piss Lost World/Forces GHZ designs. Ekkk.
