Manon Floreat I'd think about and some warm and bright colors to combat the dark cold feeling. Saturated oranges, yellows, blues, etc. Mirrors will help with reflecting light - although that may be such a great idea fro a rumpus room! The addition of good lighting and lighter window treatments will also help. Here are a couple of ideas that you might like.

rosariaabc Thank you really like industrial chic basement

NexTrend Design I see a window there... good! Is it facing north or which direction is it? Are the doors & trim throughout the house all dark brown? Light doors & trim would help alot. Lighter happy paint colors, such as butter yellow or limon walls would bring a sunny warm fresh feel to the room. Try some punchy colored feature walls as shown in Manon's above photo (thanks Manon). Get new furniture & some fun colored art & accessories, everything's looking very dated. Better lighting & a tall floor lamp that spreads light across the ceiling or corner. Lighter drapes (with grommets) down to the floor would help OR Roman shades or 2" faux wood blinds covering just the window would modernize the space and give you more wall space. New flooring in updated colors such as white-washed gray driftwood. Designate areas or stations in the room for different activities, such as floor games in one corner with colorful interlocking foam floor mats, comfie seating (bean-bag chairs) for movies in another area, table & chairs for table activities (coloring/puzzles/games/crafts), etc.

Are your children boys or girls? That'll make a difference in what you choose and how you put it all together.

rosariaabc Boy and girl, thanks for great ideas!
