Convinced a buddy to play Persona 3 (and 4, once he's done with 3).

I am made of win.
Mages in D1 have a few issues; notably that they scale far worse in damage than melee. D2 remedies this by, unfortunately, making casters amazing. Anyway, Chapter 5-3 (Terrible Cold; just combine everything onto the only non-invulnerable spot) or 9-1 (Valgipus IV) are the best spots for levelling ... though the latter requires a 3x3 attack (Sword-Winged Slayer, Fist-Big Bang, Spell-3x3). Well, CoO3 is better if you have that unlocked (and is also a 3x3 level).
[spoiler]Jessica has a 3x3 naturally as well.[/spoiler]
Incidentally, Tera Star, in the PS2 Disgaea at least (not sure if in the PSP or DS ones) would IGNORE EXP+50% GeoEffect if used as an AE. Was kind of weird. That and the animation taking forever-and-ever-and-ever (compared to Giga...) made it pretty bad for level farming.
Anyway, about to start Ar Tonelico 2 (...when my copy arrives T.T). I want my innuendo based gameplay. Eternal Sonata (PS3) or The Last Remnant after. Hopefully I can keep these games to last until end of February and Star Ocean IV...
