Gaming & Living room design

I need help designing a gaming/living room on a budget. I am looking for a modern style, with individual items included, while keeping the cost to a budget friendly level. The space needs to combine comfortable living elements with break-out gaming areas. I am open to ideas but I envision a nice balance between sleek and inviting features. The furniture and accessories must fit within sight lines carved out for activities and conversation without being too busy or cluttered. I am open to guidance from experienced designers in how to make the most of the space.
