So I had an idea that kinda stemmed from that one I talk about all the time on this thread.
So this group of friends find this… something. I’m tempted to say “game”, but that’s a cop-out and sounds a lot like SAO which I hate. I can’t say a virtual world because at that point I’m just ripping off my inspirations. For the sake of conversation, we’ll say “technology.”
So this group of friends find this technology that’s kinda like VR in the sense that you yourself are put into the (dare I say it) “game”. Everyone gets into these wide motion control chambers, and then the “game” starts. It seems to be set in famous cities around the world, and giant monsters come to attack. Everyone’s got a role based off some kinda class (archer, mage, paladin, warrior, the sort), and the pretty much fight giant monsters. When they get home, they see those same cities having been destroyed by something, but nobody can identify it. They all shrug it off and play more, finding more people for their squad across the world.
Eventually, one of them gets killed in-game. They all exit their chambers afterwards, and… they aren’t there. They watch the news that night, and their friend is shown as one of the casualties. This is no game. This is a very real thing they are playing around with, and it breaks them. They spend weeks not going near where they found the technology in fear of what might happen to them, but eventually, one of the other “players” (note: most of the other “players” knew about the reality of the technology) comes over to their side and begs them for their help again. They were the best team, and cities are getting overrun and weird things are happening.
I haven’t thought of endgame stuff, but I just wanted to throw that out there.
