This was inspired by MarvelvsCapcom2's lighting thread, but it made me think what I wish I could do with my game room versus how it is right now. I thought it would be fun to hear how other people plan or wish they could improve their game rooms as well. Here is what I could have if I could right now.
More Space: For probably the last 5-years, this has been an ongoing issue that has forced me to get very creative on how to display as much of my stuff in my game room as I can. Unfortunately all the creativity in the world will not allow me to have my entire collection on display mostly given the lack of space I'm currently working with. My game room is in a roughly 100-square foot bedroom. There is literally no more wall space for me to add shelves to house games, and I am currently close to running out of room on most of my shelves. In probably a year or two I will likely have no more shelf space on several of my shelves, requiring that I figure somethings else out given the ever expanding nature of my room. Ideally I'd like to have around 200-250 square feet to work with as this would allow me to have enough space for everything I'd need and like to have in my game room, and allow me plenty of room to show off all the consoles collections I have.
More Shelves: Going along with more space, I've always tried to organize my collection by having specific consoles on shelves that adequately hold a specific or a few specific consoles that are related in some way (having Sega Saturn and Sega CD games on the same shelf, or one shelf for all my PS2 games). Sadly, because of lack of space I've had to purchase several large shelved and throw many different console collections on them, many completely unrelated. I've still done pretty good in terms of keeping things organized the way I would want, but I do have one shelf in particular where my NES, SNES, Genesis, 3DS, GB, GBA, XBOX, XBOX 360, Switch, Wii, Wii U, and Gamecube games are housed....yeah. I would someday like to have this broken up in 3 or 4 smaller shelves where I could place these collections in a much more organized fashion on individual shelves. That's not to say I don't have any need for larger shelves too; many of my Playstation collection are massive and continue to grow. I have a very large shelf that has worked great for my PS2 collection, and would like another one just as big someday for my PS3, PS4, PSP, and Vita games to go on. And finally, having more shelves gives you more space on top of them to display cool swag related to that console such as console boxes, collectors editions, action figures, statues and all kinds of other awesomeness.
More Sega Swag: As much as I adore Sega I have a startling lack of Sega related merchandise on my game room. Meanwhile I have a ton of Nintendo related stuff. Again, needing more room and shelf space someday, it is my goal to amass a lot of Sega related swag for my room. This included figures, plushes, statues, promotional items, and other cool items to display.
Better TV and console management: What I mean by this is having a better system for how my consoles connect to my TVs and also having better TV stands to place all my consoles in so they can all be easily accessed and used at the push of a few buttons. I'd like to purchase a receiver someday, most likely two that connect to all my consoles and connect them to two or three TVs. Currently my consoles are all on two TV stands, both which I've had for years, and they don't allow me to have all my consoles out at the same time. Likewise, I am required to manually unplug one console so I can hook another one up due to lack of inputs. Someday I'd like a large media cabinet where all these consoles are housed along with the receivers so they are all accessed easy from there.
