I looked at that game, but a first glance at the FAQ suggests something very demanding. I know, I know, one always has to dig deeper to find that trove, but there's always times when first impressions and ease of use and understanding matters.
How should I put it, umm... on the topic of an MMO-ish FS? Sure, some hardcore players would gladly raise their hands, but at the same time don't neglect the casual ones who would play the game once or twice a month because they lead more... "interesting" lives. (It'd suck to fly around for fun with a couple of friends you personally know, taking on NPCs and stuff in a mid-high ping environment, only to get shot down for no good reason whatsoever...
Something easy to jump into, basically what FS has been. My friend still can't fly very well, but at least he can
fly and take simple evasive actions.
(sorry OFT: what's IDK?
