Fallout 4 is built with very similar technology to the Skyrim Special Edition.  All indications are the Switch Skyrim is built on the Special Edition version of the engine.  I mean, the Fallout 4 engine is just a revision of the Creation Engine which was a revision of a Gamebryo engine version that was itself just an engine update from the Morrowind version of the engine.  I feel fairly confident Fallout 4 on Switch could be done.  It would look different, but I am pretty sure it would work.  It's a question of smart optimization.

Fallout 4? No, no no. A Fallout 3/NewVegas doublepack.

Hey, good on Nintendo on making the effort to start the conversation. They should be doing this with other developers. That would be good...

And yeah, I'm up for seeing what else Bathesda can bring to the system. Definitely an okay from me.

That's precisely the problem; Fallout 4 is trying to do more while still running on what's ultimately a very dated engine. The end result is a game that has performance issues despite fairly sub-par tech, and by extension far less wiggle room on the Switch (especially with the CPU, which appears to be the current bottleneck). The underlying game is definitely doable on the Switch in some form, but without a major engine re-work i think it'd just be a mess.

And, tbh, there aren't many FPS like DOOM in the new gen. It's a different beast. It's very focused on the campaign, its rythm is more frenetic, and it has an old-school vibe that isn't common. 

This relationship with Nintendo is very unexpected. I'm still on shock that Bethesda (a company who rarely has anything to do with Nintendo) is committing and putting out far more content on the system as opposed to others like Capcom and Square Enix. I'm sure they'll follow suit soon, but it's just shocking.

A major engine rework would entail writing most of the game code from scratch a second time, so that it works with whatever engine they go with. Then they'd have to reimport all the sound files, all the models, all the textures, and all the animations into the engine. Considering that Fallout 4 was just a quick sequel made with existing assets Betheda had on hand, it would be *more* work just to port it to Switch, in a new engine. 

Oh and, yeah the reason why Betheda games have so many bugs is because they're using the same old code from 1999 for all their games. It's just been modified umpteen million times, to the point where nobody really knows how it works. They really need a whole new game engine, and they need most of their coding assets redone from the ground up, with nice clean simple code. 

Well Doom is an excellent game. I will definitely support it if there's nothing drastically problematic with the game. Skyrim is a game I really want to support too. However I thought about extensively, and I never had any interest in it and I probably never will purchase it on any platform.
Bethesda's enthusiasm along with ID Software's is very well appreciated on my end. Hopefully the dev porting Doom (I forget its name, but I think its the same guys working on Rocket League) does a great job optimizing for the Switch.

As they make games with the PC experience at the forefront of their minds, this could definitely be true. They'd basically just have to tone the settings down to get it running right (recent DF video suggested about PC medium for PS4/Xbox1 and low for portable mode Switch) and, from there, optimize the experience. It probably would indeed be a similar experience for them.

They want that Goldeneye type spot in the Switch Userbase.
