I tell u, FTL is really easy to mod. If u ever going to start modding at some point, this game is a really good choice to start.
Weapons modding are not hard, once u know how everything works, its really easy to mod weapons, ships and graphics. The only thing harder are the events, since they are really tricky and sometimes a missing character can make your life a hell. And once u have a really big events file, its really annoying and frustrating to try to navigate along the entire file just searching for wat u want.
About unlocking ships.. lol, i think almost everyone that entered the mod community has unlocked all the ships. That is a MUST if u going to install almost any mod. I mean, they just used a saved game editor to do it. If u going to try at some point any mod, u should do that, since unlocking all the ships is really really hard, and maybe by the time u do that, the modding community is already extincted LOL.
Its too bad, since one of the greatest failures of FTL is not to be allowed to ADD new ships, so people who just entered the modding world automatically used the save game editor to unlock all the ships, since they will need to do that in order to install almost any mod.
