The only reson why SoA wouldn't look as good on PS2 is laziness of the developers part. SoA's graphics were simple, but subtle and elegant. There isn NO harware reason why Grandia II looked bad on the PS2, and there is no reason why SoA should look bad either. If it does, I wouldn't buy the game out of principle. Heck, go out and get a Dreamcast and a copy of SoA, it'll cost you about the same as just getting SoA for PS2.
