Lord of the Rings The Hobbit, The Silmarillion: Middle-Earth, By far the best, most detailed world I have yet encountered. Tolkien did an incredible job of meshing folklore and legend into a beautiful, deep world, rich in history of its own. It is believable and logical, its cultures realistic and crafted to the finest detail. It has its own language to boot. Tolkien shaped fantasy as we know it today...
Harry Potter There is no doubt in it....... though it's dangerous and scary too.....but that somehow makes it beautiful I remember when I was 11-12 years old And after watching Azkaban I so wished to be in that world Plus they have prom nights and I would love a witch moving in my arms haha
Basin City (Sin City) Hill Valley (Back to the Future 1+2) Gotham City Twin Peaks Blade Runner version of L.A. Gattaca's fictional world (I don't think it was ever specified where it is) Rapture (Bioshock 1+2) Lost Heaven, Empire Bay (Mafia 1+2) Vice City (GTA Vice City)
Hyboria no doubt. I was obsessed with Conan as a kid and after reading Robert Howards stories, Hyboria still holds the #1 spot.
Rapture - Bioshock (as @AngelofDarkness said) Angel Island - Sonic 3 and Knuckles Metropolis - Superman Onett - Earthbound Springfield - The Simpsons
Tamriel. Sky palace mods. I mean living in a palace in the sky using a mod and having insatiable followers also via mod just had me so absorbed in a way no other game world could. I am ashamed to say Azeroth is also an answer I should answer with due to the amount of hours I put in there. And whatever universe EVE was in I guess had me feeling like I was in a special place. I suppose the fact I wasn't alone made it feel more special than it actually may have been.
I read LOTR as a child. Wonderful. Now, I think more about the future of our real world. Probably boring, but imagine if we did a better job right now...
I really like the dystopian world Suzanne Collins created in The Hunger Games series. Of course I wouldn't want to live there, but it's a really interesting story.
I like the period of iron and stone, but I'd like a bit more decent medicine and social welfare, so Game of Thrones but set in...1950? No idea.
I like different fictional world. For example Lord of the rings, Harry Potter. But I am bad writing writing compositions. I tried to write my own stories in past and posted them on website for writers. But people said me that my stories were bad. At the university from time to time I used help of EssayShark or other people helped me wit h my essays.
