An era doesn't end with one person; it ends when another begins. You started an era of scientific deckbuilding, and there are many left who employ it and keep that spirit alive.
If it had ended with you, it would've ended a while ago when you became much less active.
This isn't a loss; everyone have to focus on real life in periods. That always fluctuates. No, the community gained from having you and what you brought here stays here.
That's how a community develops. It's organic, and we're all part of it. You can always return to see the traces you left, as we all can.
