Thank you for that brilliant informed critic Dr Lexus
Am I misinterpreting you or are you being douchy? From your changing requirements and varying renders, it seems that you arent really sure what you want to do with your space. If it were me, I'd welcome others' input rather than possibly effing myself later. And, that's all I'm offering.
I've gone through this process and came out with a pretty cool multipurpose basement that even my wife and kids love. I don't have a full arcade - that's a major difference, so maybe we aren't speaking the same language, but there are some similarities in what you want to do and what I've done.
We have a theater area with a 100+" screen, a bar that seats 10-12 with lotsa beverages (2 taps, a beer cooler and a mini fridge), 2 pub tables and some gaming; MAME, virtual pinball, shuffleboard, foosball, xbox, etc. We've been able to have guys nights, ladies nights, poker nights, thown kids parties/sleepovers, and enjoyed NYE parties with thumping music, DJ lights and fog. And for hanging out watching football, baseball, hockey, etc., we've got 3 viewable screens. Point is, its multipurpose, which I think you wanted at one point.
If you don't appreciate the feedback, I'm okay if you choose to ignore it, but no need to be snitty about it.
