Do you have the exact difference listed somewhere?
It might be better to tell this on the website too, because when someone suggested Gemini Gold to me I noticed the link to Remake and also wondered about the difference.
Has anyone ever killed a dralthi when it's not firing at you? The only way I can hit a dralthi is to wait until it flies directly towards me and shoot, preferably with a photon torpedo, even when flying in a Centurion with multi-thrust enhancer. But this vessel makes so many impossible...
