My guy, more than likely. If I saw Elden Ring in the name, is expect Elden Ring. Not everyone does a lot of research because of spoilers or new mechanics they just want to see. When you see Elden Ring, you think "more Elden Ring to go through".
If Stardew Valley 2 was coming out tomorrow, I would just hope it's a proper sequel. I'd probably watch the initial reveal but that's it. If it semi-sorta looked like the original with more to do, I'd buy it. If it came out and it somehow was a visual novel without any gameplay, I'd be pretty ticked off and wonder what it has to do with the series.
Other games, people research a lot more especially new IPs. There's no initial experience.
