It had a yellow/orange cover. I read it tons of times as a kid and would love to find this book again. Here's a few more details:
Going into virtual reality or VR as they called it involved getting into a VR "skin"-suit, like a scuba-diving suit with goggles and whatnot. One story was basically teenagers getting into the VR world where they could modify their appearances to make themselves look cooler with wings or whatnot, and getting to meet their friends in that world.
Another story involved an internet VR cafe, and another had a DnD-like theme with the characters trying to get into a castle and defeat a monster.
There's also another story where the characters flew dragons (? or some winged thing) in VR, and something else involving the protagonist visiting Lilliput as described in Gulliver's Travels.
I actually read the thread here Story about getting trapped in virtual reality labyrinth where they talked about the story Shadow of the Minotaur. I read the first chapter and it sounds incredibly similar to what I describe here, but the book as I remember it was a collection of stories and not a standalone book.
If anybody could help, I'd be so grateful. Thank you!
