Launch lineups have been underwhelming for 20 years. The last system I was really impressed with was the original Xbox and only because of Halo. Microsoft could have hit a homerun if Infinite was ready and an actual good game. PS5 has a solid lineup in comparison to the last two generations. Spiderman was a huge release for the ps4 and any follow up is a big deal. If DS remake was cross gen and offered a year or two ago everyone would be going nuts about it's release.
This gen is particularly bad though.

On the Xbox side, the one thing they have going for them with the Xbox Series S/X launch is backwards compatibility and the continuation of the online communities they have built up for series such as Halo, Gears, Minecraft, Forza, Sea of Thieves, Destiny, Fortnite, Rocket League, Call of Duty, etc. So once players finish with the meager offering of the launch games, they can go back to their favorite online games or revisit old single player classics.
