Xenoblade Chronicles X
It's pretty cool how you can just enter different regions that you would think aren't accessible. I forgot what it's called but the one that looks like an alien base and has the white colour on the map, starts with S. I showed up in that place, planted a probe and ditched. I wandered into Oblivia as well, it had good music.
I only went up one level but I spent like three hours running around opening treasures and planting probes. I barely fight any enemies so that'd explain it. I completed some affinity missions too I guess. I'm nearly BLADE Level 4 which is nice since those Lv4 Mechanical treasures annoy me for being impossible to open still, I haven't seen any Lv4 treasures of the other two varieties yet so I'll leave them for later.
I guess I'll do Chapter 4 soon, looks like I get to explore Noctilum, I didn't go far past the first probe point last time.
edit: This game doesn't really have a fulfilling story, at least not yet anyway. Seems like most of the enjoyment comes from completing the map and getting those gold emblems, which makes me think I might be fine with trying to do just that. Hopefully there isn't any missable quest bullshit though. I don't really want to run around the town getting the NPC's in my affinity chart though...
