I saw this mentioned by Lar in an interview with Eurogamer:
"Nobody believes us but we really don't have anything planned. This was all in for us. This was part of our plan when we started to go independent, that we'd make the biggest RPG we could with what we had in terms of money, and then we'll see what comes out of it.
"So we went all in. We have to pay back our debts now, because we made a lot of them. It looks like that's going to happen. And then we will see. But for sure we will make a big fuss of whatever it is when we announce it."
Vincke then said he plans to try to obtain the license for a mystery role-playing franchise - but stopped short of saying what it was.
"There was a certain license we tried to get, but they haven't replied to us," he said. "Maybe now they will reply to us! I'm not going to tell you, because that will ruin the chances of me getting it.
"We asked them a couple of months ago, so we'll ask them again now. Maybe they'll be interested. It's in the RPG space, that's for sure.
"If they refuse to answer this time I'm going to put it in the press and then hopefully something will happen. Or I'll launch a Kickstarter and say, this is the game we want to make, but we don't have the license yet. But maybe we can get it this way."
Could this license be Dark Eye? I would really love a sequel to Drakensang: River of Time by Larian.
