I'm flying according to the so called EVE Ironman Challenge.
This means that I must receive no help from any player and find my way only thanks to NPCs.
For instance: - I can't buy stuff from players on the market or by contract, only NPC sell orders (like skillbooks and BPOs) - I can't sell stuff to players, even expensive loots. - I can't join a player corp excepted mine, staying alone. - I can't receive fleet bonuses or remote repair/boost. - I can't dock or use services in player owned structures, like citadels.
That means that every ship I fly was given out by a NPC or built by me, from scratch after buying the BPO or having been granted a BPC by any game mean (like LPs or carreer agent), same for modules, or rigs.
So far it's hard but very funny. Even though flying in a T1 BC, even once, means building it from a > 500m BPO, and flying in a faction or T2 ship implies gas, reactions, planetary stuff, invention, BPOs for parts, and the like. (I did not yet search for the path to T3).
