Yeah, I collect Jag games, though there's a few I know I'd never be able to get myself to spend $ on. A few of them go into the hundreds, like Battlesphere & Aircars.
As for Super Fighter, to my knowledge, it wasn't Songbird, but just the Super Fighter Team that was supposed to release a Turbo version, I have no idea what happened to that, or the Turbob version of Frog Feast.
