I'm on the fence on these two games and I have been for a while. Since these games are still available and will likely skyrocket in price when they're out of print for good (because I know Disagaea's been reprinted), are they really games that I must own? I don't have much experience with turn based strategy apart from Advance Wars, Fire Emblem, and Metal Gear Acid... so how are the storylines in these games and are they definitely worth buying, or are they just games that are pretty good, but not really necessary?
