Real quickly, I was wondering how much on average (by any barometer, such as eBay for example) do these US games complete and in very good condition -- how much do each go for, on average?

-Power Stone 2
-Giga Wing
-Giga Wing 2
-SF III: Third Strike (I heard it went down from its insane prices due to the PS2 port -- how true is that statement?)
-Marvel vs. Capcom 2
-Project Justice
-Spike Cannon
-Last Blade 2
-Fatal Fury: Mark of the Wolves

-not a game but the Sega Light Gun most use for games like HotD 2

Thanks!

Also, I bought the following today -- anyone like to pontificate a little on these DC games?

-Quake III
-Unreal Tournament
-Virtua Tennis
-Rayman 2
