Me trying something

So I've thought about what I could do for the next game before (or after) I release my big project (kept under wraps until it's finished), and I thought of maybe doing something exciting. I had originally envisioned another arcade like game but then I thought about it a lot more and I wanted to do something I hadn't really tried before. Most of the games I make are level based and linear, but I wanted to stray from that for this occasion, I wanted to work on something not so level based and instead focus on an open space game where you can explore the world more while still making some sort of progression, and I think this could work. But should I try to do it, or should I instead do a more linear game?
