Addition to our home will have a 25' x 26' open basement room with 9' ceiling.

In addition to setting a comfortable movie/tv area with sectional couch and a raised couch behind (8-10 sears total), we would like to make the rest of the space for sports and exercise.

Exercise would be pull up bar on ceiling, mats, ropes, few kettle bells, space to stretch. No large gym equipment pieces.

Sports would be whatever kids can come up with in 9' ceiling space: hockey, dodgeball, small rock wall, ropes, etc...

Flooring we're thinking about plank vinyl. Open to other ideas.

Walls, what do we instead of drywall so it can take the abuse but still be finished reasonably well (paint, decals,...)?
