glass-an existing league that offered to add sixes
-a nebulous alternative with few details
i distinctly remember that the reason people chose rgl was because they announced their league first. as in, rgl announced that they had everything set up and gave a date for s1 to start about a week before any of the other leagues did (i assume the other leagues were working things out and trying to make sure the logistics were set up for them to function). By the time the other leagues announced, rgl had already gotten a lot of support. ironically, rgl had to delay the season by multiple weeks anyways and started a month after their initial announcement bc of problems, but nobody cared about that and nobody switched.
