OP, I can understand where you're coming from, and I can feel your pain, unfortunately, the way this game is built, I just don't think it will ever really cater to your style of gameplay. As an example, I have over 1000 hours already invested in this game, so 68 doesn't really sound like a whole lot to me. I get it that you don't get a lot of time to play and that's really shame, because Elite Dangerous is a great game, but it does require one thing to be really thoroughly enjoyed, and that's time. There are really many games, if not most, that give about 60-80 hours of gameplay, and that's it, but that's not the direction Frontier decided to go. I think they've really tapped into the demographic of people that want to live and inhabit a Galaxy permanently. I've heard of people with 4000+ hours invested in this game. This is what people like me do in their spare time, we don't watch much tv, don't play many other games, we spend our time in elite. I've lost 68 hours as well I'm sure, probably more if I think about it, that's kind of just how this game is made, it's kind of unforgiving. Don't feel like I'm trying to downplay your loss here either, 68 hours is worth more to you than it is to me, I have hours to spare. All I'm trying to say is that Elite is different than other games, it's punishing at times, I can remember when I first got a type-7, I destroyed it 5 days in a row, I was barely hanging on, I nearly threw my controller through the window, but that's why I love this game, it can instill real fear in a player, especially at the lower levels.
Don't quit OP, keep playing, you will get better, I promise. there's a certain point you reach when things get much much easier. Also the people at Frontier are really nice and they don't want to lose people like you so I bet if you petition them with a ticket they'd give you most of your credits back, seeing as how they just made the NPC's much harder and all.
