Lets look at the reality here shall we lads and ladies and those who identify as kitchen appliances.
We finally get a continuation of this story 6 YEARS later. Yet in that time the Devs have been working on other projects and putting out said projects, most of which are niche and are goodish but not all that great.
Let's say, hypothetically here, if we had gotten an update to the story in say year 2 of 6: Well, hype and interest would continue to grow, stirring more fans to support the story and game, etc. etc. Yet, we are 6 years removed for that. Most, like myself, have completely forgotten about this game entirely and are just now returning to it. That's a really bad optic for a game that, while somewhat niche, had a solid story and characters to boot... 6 years ago. Now? Maybe not so much.
So sure, Mortze and Thaero have put out some game since then, show casing they are "working". Thats all well and good. But at the same time, rather than strike while the iron was hot with this one, they let it go stone cold till about a year ago.
