They're basically the same game. The layout is all the same, they're just about different things. Fallout 3 or New Vegas and Skyrim all look the same. I didn't play before 3, those are different style games. But 3 and New Vegas had really good stories, and the DLC's on those games are so good. But idk, that's back when they weren't 10+ years old. The story on Fallout 4 is kind of dumb in a way but it's still super fun. If it didn't have the settlement building, I wouldn't be playing it.
My cities skyline games are as crazy as some of my box designs. I had like 100's of handmade bus and subway routes, tons of airports, idk. People would look at the city and get anxiety when I showed them how it worked. It was a lot of stuff going on. My ps4 couldn't handle it. The game got so slow that I couldn't make money without waiting hours lol. That was part of my inspiration to build my PC.
