But you still have to buy 5000 Arx to get a 50 arx decal.
Not from me. A fool and his money are soon parted, and I'm not a fool.
I presume someone's already responded to this by now, but just in case I'm wrong...
You'd be able to EARN your 50 ARX for a decal IN-GAME, by performing some regular actions - trading/hauling, destroying (wanted) ships, missions..
If there's a weekly cap of 400 ARX, it might be logical to guesstimate that 50 ARX ought to be reasonably earn-able within 1-2 days' play sessions (presuming maybe couple hours each, but maybe not even that long).
You'd not have to be any kind of "fool" as you'd "part with" no money (beyond what you've already paid for the game).
