The one that gives me most of the games I want to play.
But the new hardware is also interesting. Just want to see a few games being showcased to get a more clear picture of what to expect from next gen games.
From my understanding it's closer to no loading times. No PC game has ever been designed around an SSD iirc, aside from Star Citizen, which isn't out yet.
It's gonna be a design difference but not necessarily a speed difference. Just like in old times where they used elevator rides for loading, you'll see similar tricks. Be that being spawned in a corridor so that the world outside can load or just a bit longer black transition between scenes. The SSDs in the consoles aren't miracles and general PC SSDs are just as fast where it counts.
Loading screens in general have been phased out more and more and actual loading times aren't bottlenecked by how fast your SSD is, but other processes in the background. Loading times haven't been a thing on PC for some time now. The only time where PC gamers notice them is when console players take longer to join the lobby.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
