I think you guys kind of strayed away from the point of discussing the business model of the subject, to the point of personal opinions instead. The business model which was that Zendir was a beginner's RTP-ish project that wasn't so great, but a sequel was planned and made anyways. If extra time and resources were poured into part 1, it itself would be successful, and resulting in part 2 being MUCH more successful.
Also don't forget the RM community isn't as strict with it's reviewing as a normal game critic would be.
Also business-model-wise it's late to make a "Director's Cut" because the initial release period is mainly what matters, which wasn't that successful.
If a company made a bad game, and 4 years later decided to remake it, what are the chances it will be played/gain popularity? Not so great of course, pretty much minimum. Director's Cuts and such only work on already-successful games to make them even more successful to the newer generation, and usually as a quick cash-in from nostalgia fans.
