Yeah, the skies is early alpha access atm, BUT, is getting almost daily attention from its devs (not left to rot in a box....) so thats a good sign....
It does have a lot of obvious glitches, bugs and areas it needs polish (no female toons available atm, there is icons for them, just not playable yet as example), but hopefully by the time the game reaches beta these will be smoothed out a lot.
PVP is a big thing in Skies, with most of the map being a big PVP zone, with missions running alongside that, very buggy atm, so hard to give real impressions on this aspect.
Crafting is less detailed than FE, but the FE craft system is great once your used to it, so might just need to 'unlearn' a few things.
NPC seem much more challenging than FE, the sneaky baristas will come up behind you and are much more dangerous than we are used to here.
Overall the game is different to FE, but similar enough you have to smile at times, even seen Red Alert clan already, Smokers also have a toe in the water (i was gonna trademark Heretic and sell the name back, but not troll enough, lol).
Chat windows and the clan system are also in need of improvement, but, give Skies 6 months and if still going will almost certainly be the only post-apoc mmo worth playing.
And for those wanting to take a chance, LIFETIME membership is available till middle of next month i think, for $14.99 one off payment....
Overall, buggy as expected, but with massive room to improve and go places, with a dev team who are (at the moment) very engaged
