Description
Mod created by fedorajoe. Will remove upon request of original author.

To quote the ROMhacking.net page, "the purpose of this hack is to mitigate many of the worse flaws of Phantasy Star II in order to create an overall play experience more similar to that of Phantasy Star IV. This means decreasing the amount of level and money grinding, increasing the number of references to other games in the series, some translation improvement, bug correction, and more."
