Welcome to PAY TO RUN Adventurers League.
I hope everyone saved all the modules from Season 1 through Season 3.
Okay I'm sorry, but let's be honest. If you're that hard up that you or one of your players can't drop a few bucks (less than the cost of one beer, much less how ever else I would spend my free evenings), about .2 seconds of googlefu gets you the modules for free.
Honestly, I'm glad they're monetizing and I look forward to buying every expedition for DMs that want to run them (with me as a player of course). More money = more likely stores will have more D&D nights rather than being overran by other, higher revenue generating games *cough*Magic*cough*.
Is it nice having stores let you play for free? Of course it is. But you know what's better? Having stores that are financially stable and that have an incentive to let D&D players have more tables.
What a about a con? There might be dozens of tables throughout the weekend. That's more than a single mod.
As of right now, there isn't a whole lot of incentive to play at a store vs playing at home. You can be more selective with your group and get all the same benefits. As long as you show up for "Launch Day" you are golden. Especially if they admins can't get certs for stores approved.
