what are the titles that make a switch so good outside nintendo first party? i feel like nearly everything 3rd party i'd be interested in is also available on pc for a fraction of the price
For me it's largely being able to play games docked and handheld that has kept me purchasing titles for the system, not exclusives. In some cases, a game might also be on PC, but not Steam (if that matters to you), or it just might be shitty on PC due to performance issues.
I'll take the OP list and expand on it with some Switch-only games and the Wii U port-ups. Likely am missing some stuff:
