Let’s say the PC doesn’t count and you aren’t taking into account backwards compatibility, emulation, online play, homebrew games, and the cost/availability of games.
I feel like I’d want to choose the PS3. Like the Xbox 360 it had a decent lifespan and a lot of games were produced for it. A lot of which are already some of my favorites.
The only things that would make hesitant are I feel like a lot of modern games are larger and have open worlds which I feel like that could be nice in the long run and many of my favorite games for the PS3 have been re-released.
If joycon stick drift wasn’t an issue, it would be the Switch easily, by miles. Alas.
It probably still is the Switch but close. I’ll just grumble about getting new joycons every 2 years.
