I think it’s really interesting that the trailer seems to confirm one of the more wild leaks - that the joycons will have optical sensors that allow them to be used as a computer mouse. It would be really interesting if Metroid Prime 4 shipped with mouse support. Also, this would be pretty notable if the rumors of the Master Chief collection releasing on Switch 2 are confirmed.

Probably something like RuneScape, not because I particularly like playing it, but more so because that game is one of the least likely to ever be shut down. The idea of living out my afterlife all alone in an abandoned or offline game is terrifying.
