In the past year or so I've replayed Front Mission 3, Final Fantasy Tactics, and Carnage Heart. I never even finished Xenogears until a year or two ago. What's funny is that I stopped playing about an hour or two from the end. D'oh. Eventually I plan on getting Insomniac and Naughty Dog's PS1 games. I never played any of their PS1 games, and I love their PS2 stuff.
Backwards compatibility is important to me. I don't like having a bunch of old consoles hooked up. Old consoles belong in a box. Old games, on the other hand, can still be fun. Next generation, if all three consoles are backwards compatible, an Xbox 360, a Revolution, and a PS3 will play Xbox, Xenon, Revolution, GameCube, PS1, PS2, and PS3 games. That's awesome. Add a PC to emulate even more old systems, and you have a ton of games to play. That's not bad. I can play Master of Magic (an old DOS game) in Windows XP (or emulate it). I like that. The console companies know some of us like that, and they want to make more money. All else being equal, BC = more money. The only problem is including it cheaply.
