Bahamut is obviously a must though! I consider that and the other summons part of the main game anyways, but damn those underworld caves... damn them! Still the most annoying parts of the game for me.
I hit the 20 hour mark myself on the PSP version even with the battle speed set pretty high and all, so that sounds pretty good to me. I wonder how the SNES easy type compares to the difficulty of the GBA/PSP version though (which was very easy compared to Chronicles)? Zeromus still wiped the floor clean with my first attempt and most of my characters were mid to high 50's, I may have been able to take him out as I kept trying to revive Rydia when she's totally not needed in that fight, and yeah it was just chaos. So once again I power leveled up Cecil to 80, Edge and Kain to 65, and Rosa and Rydia to lower 60's and annihilated him. lol, I found it very easy to grind on the floor where the last save is. The PSP version has a fast forward "auto battle" mode you can enable by hitting select though, so that helped... I probably went from ~60-80 in just 30 minutes or an hour at the most.

Have you played The After Years Ack?
