I was reading about Monster Maker in Japanese. It's a tragic story, really. Or a story of incompetence, whichever you prefer.
The project actually started in like 1991 or so, and it had a famous producer who made good stuff but took forever doing it. Wouldn't you know, Monster Maker got delayed. Then it got moved to the Super CD, and was delayed again. Then they decided to redraw the character art, so they had another massive delay. They said in interviews that they wanted to make the best RPG anyone had ever seen.
Who knows exactly what was going on behind their doors? But I'd guess that the management at NEC Avenue lost their shit at some point and ordered them to finish it and turn it out within a few months or else. The game that came out in late '94, over two years past its original release date, was loaded with bugs and only half-finished. Seriously, there was supposed to be an equally large part-two in the works, but it was canned. More alarmingly, the game came with a small pink piece of paper saying "once you go into this one tower, don't come out until you have this one conversation or the event data will get borked and your game-save will be ruined forever." And that's just the worst of a long list of bugs.
It looks like it could have been really cool, too. I like the moody piano music and the funky pastel art. What a shame.
Anyone here play it all the way through? There's a full play on niconico, but speak of the devil, it's got a Japanese nerd talking over it the whole way (saying the most obvious crap in the world, too).
