Mate no offence but you are waffling. First you said the game has an illusory economy, then you say that things required for engineer upgrades should not be the main goal of your playtime.
So make your mind up, what should he be playing for?
You sound like you have some serious love affair going on with the game, and power to you, thats great. However, a lot of people play games, and like to see tangible rewards. Hell a lot of people dont even want them quickly, but playing 20 hours and getting nowhere is BAD game design 101, no matter how glorious and noble you personally might think the idea of simply flying around running repetitive tasks may be.
The fact is, you came across so passive aggressive bordering on wanting to basically tell the guy he is wrong because he doesn't play how you play. That is your business. He said he was a beta backer, i notice you didn't really comment about that, you just picked the parts you thought you could formulate your best "play for fun not for rewards" speech on.
Sorry mate, you might, but most people don't play games that way. Just accept it and maybe tone down your posts right off the bat, instead of coming across like a hugely unemployed fanboy. I am not saying you are, but thats how your comment came across to me.
Even Brett C said it was a well written and constructive post, and it was.
