Pretty much anything modern day, minus maybe cellphones and such (the phones are big and clunky, but they can be portable). Televisions are also a thing, though picture isn't the greatest.
Just use your own judgment. If I find it too advanced, I'll let you know.
The cure one is already filled up due to character count, but you are welcome to come up with your own plots. Minor plots don't need to be submitted, but if you feel your idea is major enough, be sure to fill out the form for approval.
As more and more areas, races, and species present themselves, I'm sure more plot opportunities will as well. Remember that there's no character limit, so long as characters are of an approved race, so I suggest having more than one so they can interact and do things when you aren't near other players' characters.
Also wanna take this moment to remind everyone to continue doing what you have been: discuss, discuss, DISCUSS!
I want to see tons of plot ideas and what you all have planned for the future.
That being said, I'd also like to point out the recently added Organizations List, which you can find the link to on the hyperlink collection at the top of the first post. That's for creating major organizations and / or things like guilds and such. There's small form for it, but once your organization / guild is approved, you're good to go.
