I got XI physically but XI S via PS+. When I realized recently that it's no longer a part of the PS+ catalog I was rather disappointed. After all, I was post-game with everyone at lvl 99. It was my perfect save.
Fortunately it's at a pretty decent discount on PSN at the moment, so I bit the bullet and bought it.
Yeah, I remember being kind of annoyed that you couldn't unlock all skills by simple virtue of being level 99. I'd have to check. I honestly don't remember if I ground for skill seeds or if I decided to leave well enough alone. By the time you reach level 99, you don't really have much to worry about.
Right now I'm at work just dying to get back home. As whiny as I might have sounded in my past couple posts, I am excited to get into a new DQ game.
