Tee's Entertainment Room

I am a gamer, game and figure collector, book collector, and entertainment lover. I have a decent sized space that I would like to set up. The space is very specific in shape, and I have alot of figures, books and a large game library that i want to display. i am exclusively a console player - no pc and multiscreen setup. I need it to sleek, not boring, and full of character. I have a wooden coffee and side table set that are an essential part of the setup. There are a few IKEA floating shelves that can be used, but not necessarily. natural light in this area is ample, so I need something that is cozy in the evening and not too bright during the day.
TV, 7.1 surround system with wall brackets and standing pedestal stands for speakers all are available and must be used.
