Assuming the equipment was also saved so you could still play the games, and every game in existence you don’t mention gets permanently destroyed, and no new games are ever to be made.
Inspired by a video by OutsideXbox from a few years ago, I thought it would be a fun idea to see what this community would choose. You can choose to be selfish and pick games you personally want to always play, or try to figure out what games would be best chosen for humanity to save for whatever reason. I’d also love to hear why you chose your games. Do they have a special meaning to you? I want to hear your stories.
TitanFall 2: Its the Portal 2 engine, but better. Also runs on almost anything these days, looks good, could easily be a basis for a ton of different kind of multiplayer shooters via modding. You could basically rebuild any Source game/mod between 2000 and 2015 ish in it.
Deus Ex (the original): Lower fidelity but that means it can run on more things, is also highly moddable, also has a working multiplayer framework that it’s had since almost day one that I guess everyone forgot about, could also be modded into nearly anything, including lower fidelity than TF|2 multiplayer games of basically any kind.
VintageStory: Minecraft, but better. Also highly moddable. Also networkable.
Fallout Online (2/3): Assuming the likely near apocalyptic setting accompanying this hypothetical, we’re gonna want a 2.5D turn based tactics platform, FOnline is highly detailed and highly moddable, and is networked. You could also basically rebuild nearly any 2D JRPG in this, yes, even Pokemon, if you can handle 2.5D isometric sprites.
(I was originally going to say either Xenonauts 1 or 2, but then realized you could basically build X1 or X2 in Fallout Online, and FOnline is already networked.)
No Mans Sky: Beyond being essentially the most advanced procedural generation game that I am aware of, in breadth and depth, you’re going to want to have all that code to be able to decompile parts of it and thus be able to rebuild other or new digital worlds with it.
I reject the concept that no new games will ever be built.
I’ve been using and making mods since the 90s.
There will be new games, apocalypse be damned.
Also, as much as I love some Bethesda games, their engine is a heap of broken garbage.
Rebuild FONV or Skyrim in TF|2 or Deus Ex instead.
They are entirely capable of being modded into that.
