Project man cave..

[Danube_3KGT]

So, My fiance brought up to me, the idea of making a spare bedroom we have into a man cave.. a room me and my friends can chill and play video games and what not.. Im kinda looking for ideas from people on what I can do.. Im Irish, and I want kind of an irish inspired cave but i figured getting a bunch of people thinking would bring a lot more cool ideas..

Im thinking about a dark green, almost black dark green or blue

and then putting a shelf around the top of the room, about a foot maybe to from the ceiling and putting liquor bottles on it around the whole room.. all kinds.. like Jack, Red Stag, Jager, ect.. possible with like an LED light rope behind the bottle to help light em up..
