When it actually came to the time to ask I'm not fully sure what to inquire too, hahah. Is it fun and do you enjoy using certain types of weapons more than others? Also, since european longswords aren't really available in my area, do you think I could replace it with, say a katana, and do the same drills as for a longsword?
Thanks Cameron! 
I am inexperienced with European styles. For non-European styles for fun and defense, I suggest you look at the broad family of Philippino stick/knife/sword martial arts: Kali, escrima, and their various subsects, like pekiti tersia. Their moves are interchangeable and there are practitioners who can teach. Unlike many other arts, these are less-pretty more-effective arts with simple, stackable moves that are effective open-handed, with a car key, a screwdriver, or a stick, in addition to edged weapons. They are practical and evolved, so there's more subtlety than there appears.
YouTube them and find a practitioner. Lessons are not expensive and they are all good exercise and hand-eye coordination builders. I am renowned among my friends for little tricks of the hand (swatting bees from the air or catching dropped objects) - and it's from my training and practice. See my poem on the Peaceful Path for my summary on the subject.
