I'd buy any 2D Fire Pro at all, as long as it kept the same stats/attributes system, the same timing-based play mechanics, and has allows you to create new wrestlers. Just to support the game series.
I'd pay a PREMIUM (100$ +, 150$, I don't care!) for something similar to the FPHD hoax features.
Unfortunately, the video game world has changed, and there's very little place for works of love such as Fire Pro nowadays. Fire Pro R was basically done as a fix for FPZ, a proper swan song for the series...
Plus wrestling is in a rut. Outside of the WWE and TNA games, I can't remember the last wrestling game that was released on consoles. Japan doesn't even produce licensed games for their feds anymore.
We lived through the golden age of wrestling gaming, and truth be told, we should probably enjoy the WWE games more than we do, nowadays, they're pretty impressive. Yet, today, it's FPR that's playing on my old dusty PS2...I suspect most of us are really, really nostalgic about the good ol' days.
