The gravitational effect is the only prerequisite. The WIMP theory predicts weakly interacting dark matter but even primordial nucleosynthesis does not require weakly interacting, just that it be nonbaryonic. So only if WIMPs are right is it going to be weakly interacting.

Done and done! Big SC2 fan. Now I’m just waiting on my swag :)

I 've been playing minecraft bedrock using the steam deck, over LAN with my daughter on the Windows PC. We needed two Minecraft accounts $29 from Microsoft. The deck controls worked identical to Xbox controller once I loaded the Minecraft bedrock launcher from the discover app and added it as a non steam game to game mode. That was the key to get the controller to behave right. It all works like a dream now and is super fun!

Thanks everyone for the educational responses! My daughter and I are now happily playing in one of her bedrock worlds on LAN using the steam deck. Steam deck setup for the bedrock launcher was a bit tricky but now it runs awesomely, in game mode, and even has the exact same controller setup. If anyone is curious about how to set this up I’d be glad to help, I had lots of tricky missteps on the way, but I got there.
