This is similar to my experience. A few games came and went that I was interested in but not a single must have and I don’t think I ever did more than install a game and try it for 20min and then lose interest. I would just keep signing up over and over for $1 and sometimes when I’d cancel they would even refund me my $1. It was a bizarre system. I don’t even honestly think I was abusing it either be because I got about a dollars worth out of it every month.
Maybe. I have those two and a PC and I think the Deck is essential. But I do really like being able to seamlessly pick up my games on my main machine sometimes too. If I didn’t own a PC or a PC game library it might be less enticing but even then I still think it’s worth it. You may struggle deciding where to buy games though and you will probably end up building a gaming pc if you enjoy the Deck.
