I can do a bit better in the Colosseum in Jeanne d'Arc on PSP now, but I got creamed in the 8th or 9th battle and decided to go back to grinding some more. No big problem, the battles are fun and go by pretty quick, and most stages have brand new rewards in the post-game. I now have Jeanne on level 86, I believe, and everybody else is roughly around level 70. I can tackle most of the battlefields with ease, but some of the ones with high level dragons are still a pain.
I also played a little 2-player Dungeon Explorer on Sega CD. It was my first time playing the game, and needless to say, I was getting my ass kicked left and right, haha.
