The Common Room should become a retro arcade. The floor should contain arcade machines around the room that are cheap to play and continue to offer vintage consoles with more games and console offerings. New furniture should be purchased to replace the damaged sofas and the room could feature wall art painted by students, this could be gaming themed to enhance the theme of the floor. The bar could be removed to increase space on the floor allowing access to vending machines and additional space for consoles/arcade machines.
The room should retain its ability for social space relaxation and bring your own device support. Monthly events should be run in the space and make use of the hardware that’s desired, these events should become a staple to the Abertay community and should feature a rotation of games and titles. These could be leagues or tournaments.
I think this would be too niche to be profitable, but I do like the idea of having a couple of cabinets in one of the other proposed cofigurations.
