Roast Beef and Gorgonzola sandwich, Rodney. It was aces.
Clearly there is a divide between those who grew up in arcades, who played these machines in actual locations and have fond memories of them and appreciate them for what they were and want to recreate that, and those who want something awesome that plays videos game, the more the better, for their mancave. There certainly is room for everything and everyone in this hobby. One isn't "more right" than the other. I think we can probably all agree on that.
But I do take umbrage with those who think that people's opinions are fueled by a hatred of new things. New things, if implemented with care, thought, and planning, can turn out great.
For example, my favorite cabinet last year, the well-deserved winner of the UCA Blip!, did two things I don't like in new cabinets - swappable panels and an LCD marquee monitor. But he did them SO WELL, and integrated them in such a well-thought out, well-planned manner, that I fell in love with the cabinet. Doesn't mean I now care for those two things, but I can appreciate the foresight and planning - the way make did them makes them look like less of an afterthought and more like the intended design. It's a beautiful arcade cabinet, not a video game playing machine, but a real arcade cabinet.
Yes, some people probably put way more importance on these things than they should. And maybe they need to move over for the Dave & Buster's set. But like harveybirdman pointed out, there is an art to these things, and some people like to look at them with a critical eye and offer feedback and suggestions that appeal to them. It cracks me up when people vilify movie critics because they don't like their favorite blockbuster ("What do they know!"). The job of a critic isn't to tell you how you should feel about a movie, it's to tell you what THEY thought so you can make an informed decision if you want to see it. You don't HAVE to change your artwork because someone like Opt tells you to, but wouldn't the opinion of a trained artist who makes money for what he does be of some value to you?
In the end, do what you want. Angle your joysticks, collage your characters, widescreen your LCDs. This Guardian of the Hobby doesn't really care anymore. It's all about having fun, right? In the end, no one cares about the wire looms you made by hand, the light up joysticks, the ground effects package, or the artwork you vectorized by hand.
They just want to play some Galaga.
