Same here, Drizzle. When I saw the trailers, I thought, "It looks like Fallout 4 in space." That is a problem for me, because I did not like Fallout 4. I liked Fallout 3 a lot (as well as all the Elder Scrolls games I've played), but I got bored with Fallout 4. I just couldn't get into it. I think the main problems were the base-building, which felt like an annoying distraction to me, and my overall fatigue with Fallout's world and mechanics (e.g., rooting through one lifeless building after another for scrap).
When I watched Starfield trailers, I saw those same elements -- emphasis on building and crafting, tedious collection of resources, etc. The main difference, of course, is that the world(s) of Starfield will be different than the world of Fallout. Even there, though, I'm not seeing anything that draws me in. The art style seems rather dull, and the environments sterile/mechanical. Maybe they'll release more inspiring footage later.
I don't mean that Starfield will be a bad game. I expect it will review well and be a financial success. I'm just saying I don't like the Fallout 4 vibes I get from it.
