So, the thing I've noticed with this expansion is that a great many players who post here have been looking at the benefits of this expansion through a narrow lens. I think the thing that has been overlooked is how this expansion affects the game and it's longevity. In order to explain my point I need to delve into another game; BattleTech.
I have been a demo rep for that game for over a decade and the game is over 30 years old. Comparatively speqking when you compare it to things like 40k, warmahordes, x-wing, and other games it barely registers. Part of what keeps it alive is the demo team constantly working at conventions to bring new players, new blood, into the game. While it was owned by FASA there were a great many opportunities to cross market the game that were overlooked or mismanaged. Because of that we constantly work to keep the game from "graying out". If you dont know what that means go to a historical gaming convention and look at the average players age.
How does that relate to x-wing or the heroes expansion?
FFG doesn't have guys like me who are vetted and are representing thier company and games spread out across the globe. So they need to rely on keeping thier products relevant to what is going on in the publics eye even more. Heroes provides a gateway for someone who isnt as familiar with the prequels or ot but knows tfa and liked it. The new core is the same thing. While they used it as an opportunity to clean up the rules a little it is more for making the game more visible and getting newer players into the game.
I wholeheartedly support the heroes expansion as now a person only familiar with tfa can get a core with ships they're familiar with and a falcon that is relevant to them without having to spend money on a core, a falcon, and then a "cards only or most wanted style" expansion that was made to keep a bunch of grognards and neckbeards happy so they dont have to buy a new falcon for rey.
It isnt a cash grab, it's a valid effort to keep thier game relevant and growing so x-wing doesn't become a blip on the radar after a short heyday.
