Please remember to avoid double-posting. (A rule I haven't enforced as much as I should.) Triple-posting is worse than that! I've merged your posts anyway.
Skies of Arcadia is one of Sega's best. Why Sega hasn't ported it to modern platforms is beyond me, especially with the slew of classic JRPGs that have been ported over the past few years. SoA is yet another JRPG cash cow. I'm sure that it would make far more than the cost to port it.
