It's more like pay for access to a wider game. I see the ships as essentially DLC unlocks, bought a mining ship - congrats now you can access the mining mini game, got yourself a fighter, good now you can die horribly to better players slower.The pay2win argument is an interesting one and this game is definitionally pay2win, of course it is, i think it would be daft if we didn't all agree on that and when we do we can have a wider conversation about that.
So if you buy the C2 with cash then congratulations you skipped working your way up to owning that ship and you can earn a lot more money a lot faster than you can with a Drake Cutter, you win, but what did you win? You won missing out on part of the game. Well done.
There's no real end game, nothing to win. All you are doing is rushing towards different gameplay, but not actually a terminal point where the game completes.
