Cuphead is not an exclusive. It's on Steam too. The original Lucky's Tale scored a 62 on metacritic. Sea of Theives looks neat, but Rare hasn't done anything great since the N64 days. State of Decay is sitting at 72 on metacritic.
There's a huge difference between having AAA exclusives, and having AAA exclusives from developers with a track record of putting out great games. I mean, Sony didn't have much, but at least they had a new Spiderman game developed by Insomniac. At least they have DLC for Horizon and Uncharted 4. Those things are worth looking forward to because they are by developers with a current and proven track record.
