I love Super Godzilla as well, for nostalgic purposes. Godzilla Monster of Monsters on the NES is another favorite, and even more nostalgic. I wish I had a chance to play Godzilla:Kaiju Kessen (Super Famicom) in my youth, but I unfortunately didn't get a copy until a few years ago. Great game though!
I also think I'm one of the few people that actually enjoyed Godzilla:Unleashed (Wii), if not just for the addition of Biollante and Varan as playable characters. The lack of online play is what really killed it in the long run. Also, no online play=next to no replayability. The lack of Hedorah was also very disappointing to me personally (when the game was announced, I was sure he'd make the cut. He was the only major Godzilla villain missing from the final roster of G:U.
