Stone Rage will be our "next" project within the next few years

The major plan is definitely to make Stone Rage bigger, have more depth, more depth, and more depth over time. Stone Rage 2018 will be a better game than Stone Rage 2017 etc This means more game mechanics, more animals, better gameplay mechanics, more recipes, additional world areas to explore, you name it - we will ALWAYS want MORE. Stone Rage could be the greatest game in the world and we'd still be trying to figure out how to expand it and improve upon existing assets.

Workshops mod will be supported ?

That's very possible as this is an Unreal 4 game. We'll be taking things like that one step at a time though. Can't mod an unreleased title!

Definitely something we are going to be looking into after release. No concrete info on that front yet, though.
