I have had conversations with Sidular about this before and he seems pretty determined this time. He has all sorts of ideas he wants to implement. I think it is fair for people to feel skeptical/doubtful. I think the concern of relying on one person for funding is fair. Sigafoo was the primary funding for RGL for a long time. RGL has never really been able operate at a profit. It always broke even or operated at a loss.
But, I do have hopes that Sidular can pull it off. It is time for there to be an alternative to RGL for players who may no longer want to play in RGL. I know quite a few people who quit playing competitively due to RGL's staff and structure of how its managed. A huge chunk of why I stopped playing was due to RGL as well.
Best of luck to Sidular and team.
