It would be nice if Sonic Team decided to replace the El Cheapo lighting model with something more solid. Like if you're in a dark room, and look into a room that's not dark, you're supposed to see the stuff in the lit up room :/
Rafoie and Gifoie should really light up rooms. It's not all that hard, right Sonic Team?
I'm sure somebody on the dev team wanted desperately to do it, but he couldn't make it work good enough to pass muster. That's a shame, because real-time lighting from giant balls of fire would be a nice tough. I'd have taken that effect over the wavey telepipe effect.
