My plan for my dream space is that I want it to be a pokémon themed room.
The walls will be curved so that my room will be spherical. I also would have them be red and gray to match the pokeball.
My rooms purpose would be to give people a cool place to hang out and watch movies, and to play video games, have Smash Bros tourneys, and host pokemon battles. There would also be places to read comic books, but the main focus would be on pokemon.
I made this the theme because those are the things that I really covet in life: Pokémon, Movies, Video Games, Comics (in that order).
