I would like all it all (hangout, tech, arcade) under one banner. I'm VERY interested in anything 'EM' so having it all together is fine. Agree with 'newmantjn' that having sub-heads under EM for tech, etc. would be OK as well.
I spend 99.9% of my time on the two EM tabs. I even like it when people post 'for sale' in the EM section vs. the Market as there I have to shift through a bunch of SS or DMD games that I don't have interest in.
By the way, not knocking the other types of games, it's all about relevancy. I love cars and can appreciate a '30's Packard or 2000's Porsche, but I grew up in Detroit in the 60-70's so what I really like are 60's - (early) 70's American cars. Same goes for pinball (although I didn't play early-mid 60' pins much and I think I enjoy those the most now).
