Not from you guys though, right? You guys never give anyone shit about things not playing exactly like the originals, right? I kid, I kid.
A successful Gemini remake would be extremely difficult. Like Ram said, the original wasn't well-received on its own -- in part because it wasn't a really well-divided competitive environment and in part because it was released next to maps like Relic and Terminal, which were grand in just about every way. Functional things in Gemini would be tough to recreate, like the doors which open and close -- they played a pretty big role in the map's functionality. The best part of Gemini, for me at least, were the visual elements like the Prophet fountain, the Yoda tree and the bad ass view of the Forerunner dreanought parked at the center of High Charity.
I'm not sure how you could recreate any of those in Forge. Good luck though, Dax. I'm pulling for you.
