After coming here a dozen or so times since my last review, I decided to write a short follow-up.
I mentioned before that the owners seem open to suggestions from their customers, and after meeting and befriending them personally I can attest to this. They are some of the friendliest, most sincere people I've ever dealt with in my life, not to mention at a business.
A large re-organization of the games in the building has occurred, and the new layout is a large improvement over the initial one.
There are many new games and ideas in the works for Gemini, mostly suggested by its patrons. I don't want to mention anything specific for fear of any of them not working out, but know that the people running this arcade are very serious about keeping their customer-base happy and loyal.
One thing they did change recently is their hours of operation. They got a lot of feedback from their customers who wanted them to be open later, so now they're open later each night.
If you enjoy video games at all, do yourself a favor and go check out Gemini. Talk to the people there, make new friends (you'll probably find me on the DrumMania machine -- say hi!) --and if you're like me, find a new favorite spot to hang out every day after work.
