If you ask me, the fact that it requires a PS5 makes it a non starter. I was really hoping for a standalone handheld, maybe not as powerful as the PS5, but something to compete with the Switch and Steam Deck. Like the PSP was a less powerful PS2 but still a standalone handheld providing a console like experience. Or even a phone handheld, the N-Gage was ahead of its time!
It’s not a deal-breaker for me, since I already own a PS5 and I was already looking to stream those games to my computer anyhow, but haven’t got it set up well yet. There’s some weird audio stuff going on, at least.
I am also not interested in buying handheld-only games for another underpowered system, so it’s fine that it streams them from a powerful device instead. If they manage to get the battery life good enough, I’m going to seriously consider it… But not at launch.
