Sure. I don't earn credits anywhere near "as fast as possible" either, in my actual play. My normal play gets me more than enough money for what I actually spend, so while I know how to make 200M/hour I never actually have.Jokes aside, you can surely make credits very fast in ED, I just have never done it, and wouldn't know how. It is not my current playstyle.
But in an Alpha test if I need more resources for testing something I'll just look up the quickest way to get them and do it.
I am suspecting that Frontier have labelled it "Alpha" precisely because they intend to do something like the original Alpha/Premium Beta tests where the play area is seriously constrained and features are incrementally introduced, so that tests of e.g. "how does inter-player networking cope with foot action" aren't made worthless by everyone being spread across the galaxy ... and then once that's sorted, then a "Beta" where everyone gets their own accounts in a full-sized galaxy.In fact all the testers may end up spawning on a planet with no ships, it's hard to say, but there's one thing I am certain of, we are all wrong!
As you say, the only certainty is that we're all wrong about how it works.
