I really don't care if it's hard or not to port games. If it's so much work why Sega give us none of the more interesting games? Something like:
Shinobi
Virtua Fighter 4
Panzer Dragoon Orta
Toe Jam and Earl
House of the Dead 3
While we get ports of DC games and Monkey Ball games. Sega didn't even try one mature original game on the gamecube!
