I beat the Aeons last night, beat Nemesis, and Omega. Now as far as Penance goes, I fought him three different times, the last getting him down to 6 million HP, but lost. I will probably try again, but it may take me awhile as it is purely luck. What kills me, is not so much the first phase, but instead the second.
Working on completion ratio. I've got it up to 84%. Have 30+ games that I need to get them to at least 80% or better. Would like to have 90% completion ratio. It's a long grind playing old games, several of which plat is unattainable. Still will work on cleaning up trophies on those games.
