Starfield's early game choices are there to set you up for 500 hours of roleplay

Starfield's character creation system is designed to enable hundreds of hours of roleplay - if you want it.

In an interview with Kinda Funny Games, game director Todd Howard was asked how Starfield backgrounds and traits have evolved from the systems created for games like Fallout 3 and Skyrim. In response, Howard suggested that Bethesda has learned that two important factors are how those traits feel at the very start of the game, and how they fit a character rather than a stats list.

"We've done a number of games over the decades that have various character systems, and I think we've learned a lot in terms of 'how does it feel when you start a game? What are those first choices like before you understand what the actual rules of the game are?' That's always a trick to get right."

Perfecting your build before you've got a true understanding of the entire game is a permanent concern for RPG fans, but Howard says the team is also thinking about how the decisions you make at the start of the game will shape your character for dozens - if not hundreds - of hours:

"And then 'how much depth does it have if you're playing for 20 hours, or 50 hours, or 100 hours, or 500 hours?' I think we've hit a real sweetspot with Starfield, of giving you that flavor right out of the gate, where you are gonna pick some starting skills, with your background. But that also has flavor - people wanna roleplay. They don't wanna just see it as a list of numbers." 

Howard picks the example of a chef - if that's your background, how will it actually affect what you're able to do in your own story, as opposed to simply affecting various stats? We saw some of that at play in the recent Starfield Direct, as a character with a hunting background was
