Apparently the ps5 comparison is because they ran the same tech demo that the ps5 did 2 years ago. But that doesn’t really mean anything. At this point Nintendo may still be working with a wide range of specs on prototypes before finalizing a decision about what the console will be.
Sometimes windows itself will only let games know there’s a controller plugged in after a button is pressed, but connecting a controller with the game already open can usually be detected just fine.
Multiplayer makes fights more fun, but the game’s story is better experienced on single player.
When I first started playing I was mostly just using basic attacks against enemies like a regular rpg. When I played with friends with all sets of different builds I saw them dropping furniture to barricade doors, shoving enemies off of cliffs, triggering traps from a distance and all sorts of cool stuff I wasn’t even considering. But outside of fights everyone moved somewhere different and triggered different story elements that the others weren’t seeing at all.
