the first one is like what i have. spatial sequence synesthesia. it also manifests most strongly when imagining months of the year, but instead of an oval mine is kind of an arc that starts on the left and ends on the right, with a weird emphasis/broadness on april (my birth month)
They do different things for me.
PoE satisfies my creative side in the sense that I can find say, a great unique item, or support gem, want to make a cool build out of it, and give that a shot. I also love that the endgame experience is highly customizable (in the form of hideout, as well as map-running choices, atlas passives, etc)
I’m only level ~40 or so in D4 so take this with a grain of salt – although D4 doesn’t appear to have nearly the same level of customizability that PoE does, what it does offer me is an enormous world I can explore pretty much from the get-go. PoE is extremely linear, all throughout. Another thing D4 does really well is the feeling of its combat. Basic skills being a free, but weaker skill to help generate resource to more infrequently use a Core skill is a satisfying recipe, IMO. PoE would often feel like a screen clearing stomp-fest (and, at times, require it) and even though that can be satisfying in its own way, it’s more fun for me if I feel like I have to struggle and claw my way into wins.
