Growing up I spent most of my time reading, so when I first started playing RPGs in middle school and got a copy of DnD 3.5’s rules I loved their collaborative take on storytelling.
These days I like to use RPGs to develop my creative problem-solving skills as well. I enjoy trying to find interesting uses for spells or coming up with unexpected tactics.
I also like to tinker with systems. Adding monsters or alternate magic systems is a fun way for me to try out the worlds from some of my favorite books.
