the craft system is "simple" and yet VERY complex when u get into it.
very diverse world, and quite large. its not hugly populated but the outpost wars are a site to behold - 150+ players all in one place trying to kill each other and win for the attacking/defending guild (or faction )
there is no gear drops by any bosses. (except the 4 major race bosses - wich drop plans that enable players to *eventually* craft the same armour anyways)
pretty much all gear is player crafted
and recepies are fixed, but finding them is a life long quest tbh
the game is also totally free as far as "classes" is more classless, a single player *can* learn everything (not really possable to make a bad build)
but dont go thinking that it means u can just craft all your own gear, there is a great deal of time and efort required to become even anywhere close to self sufficient - but its not long before your own craft becomes usefull to others.
the other bonus for crafters is that no items can ever be repaired, so there is allways demand for new gear
the community is very mature and friendly imo aswell
(ps yes i play the game. no i dont work for gameforge (creators of Ogame) xD)
