Powerscale has great feats, he can straight up grow mountains and throw buildings. City level at the very least, I bet he he'll be tectonic / island level at least by the eos.
The intro and concept are great, and his powers feel awesome. I couldn't find a ton to do in the main area but it was fun flying around and scaling the mountains. I went to the playtest area and flew so fast the world flipped upside-down so that was cool too.
