Nice set up mate and i like your grid ceiling too.
Thanks, we enjoy it quite a bit. I'm not a huge gamer and got a PS3 somewhat recently so I've been playing video games in there probably once every other week. It's pretty fun to play Assassin's Creed or Call of Duty.
It's funny you mention the drop ceiling, that is so far the major downfall I see with the room actually. If anything is bass-y, such as explosions or music or whatnot, the subs pressurize the room enough that it'll start lifting a panel and I can hear it - it's pretty annoying. As Fuzz mentioned, I think the next project will be yanking that out and putting in good old fashioned dry wall/sheet rock.
In addition, I think I'll add a platform for the projector to sit on rather than hanging from the ceiling as is. I do not like the mount I have, it's fairly difficult to adjust and fine tune, perhaps spending a little more money would help with that but I think overall a little hanging platform from the ceiling would look okay as well and be much easier to adjust things with.
I haven't updated with any pictures in a while, I really should. I added a small riser for the couch to sit on. When we have people over to watch movies, we pull in another futon to sit in front of the other couch. That thing weighed a good 3-400 pounds I think. I should have built it in the basement but I did it in the garage then had to get it into the basement... A lot easier said than done.
I'll try to get a couple updated pics in here shortly...
