Prior to sandbox games, one started and headed immediately towards the end game. The games were short in duration at first, and grew and grew and grew. Since the dawn of games, that has been the process. Sandbox games are simular to real life in general. One can play until there actuall real life body is dead and never finish the game. It's a whole new process we are not aquainted with and takes a lot to get ones head around.
Once one does, sandbox games are the only way to go. I played NMS of 10 hours a day, 6 days a week for 8 months. And finally got bored, put it down, picked up ED, and now I play 8 to 10 hours a day, 6 days a week for the past three weeks. While both games are simular inso much as they are both sandboxed. They have their own personalities kindo of sort of. HUMANS crave more than any thing else besides food, clothing and shelter, variation. Life it self is a grind, playing a conventional game is a grind to the end. Playing a sandbox game is a grind to your end just like real life. It's what you and you alone make it.
Problem is, in real life there's phycological help with life's issues of grinding. And it has a cost to pay of one sort or another. Sandbox games, one has to rely on forums for the same data phycologist make ya pay for. But with a subscription, it's free. LOL In real life if you don't like your therapist, you can always pay another, the same goes for forums, only the next one is free with subscription also.
