I’m not seeing Elden Ring anywhere in the top voted posts, but if you’re looking for something like BotW, you should consider it. Always somewhere new to explore and very non-linear. The lore of the world is insanely rich, but there basically is no story.
Tunic is awesome. Lots of exploration and lots of secrets to find. Don’t look anything up, it’s a very unique experience.
Hollow Knight is the first metroidvania I liked. Great exploration, but it’s not exactly going to test the limits of your rig. Similar to the Souls games, lots of lore, little story.
Rimworld is so non-linear it’s literally a story simulator. It creates unforgettable experiences and has infinite replayability. You can save and quit at any moment, so it’s good if you only have an hour or two (but you could easily put hundreds of hours into it).
And I want to echo others who said Outer Wilds, RDR2, BG3, and CP2077.
I think they’re just asking, from a categorical imperative perspective, what is the most effective way for all individuals with a bit of savings to help the climate situation.
And tbh, at this point OP is probably better off spending that $10k on preparing for:
At this point, there’s virtually nothing that can be done to stop the impact of climate change, there is only adapting to survive it. The best we can do is vote and/or hope for our global political situation to finally reach its inevitable crisis point. But I don’t expect that to be a pleasant experience.
