We all know that Bethesda can craft some pretty huge games, so it will come as no surprise that their next big title Fallout 4 will have a large amount of replay value. People have likely told you stories of how they have played Skyrim for hundreds of hours and continue to find new things to see and do.

But 400 hours without seeing everything? That’s almost unheard of, but according to Bethesda’s lead producer Jeff Gardiner it is true of Fallout 4. Speaking to OXM, Jeff had this to say.

“I’ve played the game for probably 400 hours, and I’m still finding stuff that I haven’t seen.”

This is apparently in no small part thanks to the game’s extensive crafting system. Previous Bethesda games have had lots to see and do, but none have offered the endless opportunities for creativity like Fallout 4 will with its ability to customize specific sections of the Wasteland as well as weapons and body armor. Pete Hines discussed the system in a bit more detail.

“For the larger building stuff it’s not stored in your inventory, it’s in the workbench that you’re using in that area. I de-constructed this and it’s all stored over her and then when I go to build it’s pulling from that inventory of stuff I have.”

Electronics can also be installed in buildings but will require generators.

“It’s all common sense visual stuff. If it doesn’t connect to the generator, the power doesn’t work. You can actually flag stuff to say ‘I’m looking for this stuff because I want to make this’ which means that when you’re scavenging anything that fulfils the requirement gets flagged in the world. When you connect stuff to the computer terminal you have a lot of control and sort of fine tuning. If you’ve got something that plays music, you can actually define how it’s playing music.”

All very exciting stuff. Which aspect of Fallout 4 has you most giddy with anticipation?
