Phantasy Star II, called Phantasy Star II: Kaerazaru Toki no Owari ni (ファンタシースターII 還らざる時の終わりに) in Japan, is the sequel to Phantasy Star and was developed and published by Sega for the Sega Mega Drive in 1989. It was the first RPG to be released for the system and is considered a highly influential release for the genre as a whole.
The game has a nasty glitch that every player has to encounter: near the end of a game when you talk to Lutz in Esper Mansion after collecting all legendary items the music will hang on a single note at the start of a cutscene and will remain glitched. No sound effects will be heard. Other side effects can occur such as cutscene text becoming messy and the game can even crash in certain events.
Pausing and unpausing the game can fix the glitch, possibly while talking with Lutz or doing it in other circumstances. Saving, restarting and then loading a game works as well.
Interestingly enough, a single NPC in Paseo town speaks dialog lines from the previously mentioned glitched cutscene if you try to talk with him after completing Climatrol dungeon. Most likely a developer oversight.
At the time of release, Phantasy Star II was one of the biggest RPGs available for home consoles, and in turn one of the longest (and arguably more difficult) Mega Drive games. Translation issues prevented the game from being localised worldwide - Sega created Japanese and English translations, with Tectoy translating the game into Portuguese for the Brazilian market and Samsung into Korean for South Korea. As such, there was no official pan-European localisation of Phantasy Star II - only English language versions were released in that region.
Due to its perceived difficulty, the US and UK versions shipped with a map and 110-page hint book.
