I don't own a GBA or a PSP, so I've never played CoM or BBS. But I have played Days and Re:Coded. Days, I'm iffy on, but I love Re:corded. IT reminds me of the the first game. More nostalgic than Days had towrd II. I love the Matrix system, so rad. I wasn't playing very long when in Traverse Town, I unlocked Heat/Spark Sweep Lv 14. Well, I guess that depends on your definition o f playing long. I like being able to decide the difficulty I'm playing at mid-game. I forgot I set it to Critical and got crushed by final-form Darkside over and over again with a total play time of 11 min. It made me feel dumb afterward.
