Legacy mode should be made available to be played by all members of the Supremacy community. I remember reading in a post that said as of a certain date Legacy mode will not be made available for new players joining. I disagree with this decision. Let the players decide what version they like to play that does not damage their computing device or cellular phone.
Also a comment was made by a "powers that be" about the amount of money Legacy mode generates...Supremacy was touted always as a free game. If you want to play without spending a dime, you can. If you want to spend $100USD on a game, you can. If you purposely limit the players playing Legacy, you correspondingly limit the potential amount of income you can possibly receive from players.
Open it up.
Thank you for your time.
