Landing the first stage is impressive but actually useful only in so far as it allows you to reuse it. SpaceX has yet to show that they can actually reuse the first stage. It will take longer still to show that they can do it reliably. Let's skip a few steps and assume they've achieved that. That's an important innovation, it changes the economics, will allow SpaceX to drop prices and potentially grow the market substantially. All of that would be amazing and a huge achievement but it would not push the frontier, it only brings in money that can be used for projects that do that. I would argue that for this reason it's not game-changing, it's incremental progress that enables further innovation that could be game-changing.
