I have played a bunch of different RPG's on and off for the past 20 years (ie. AD&D, D&D 3.5, D&D 5E, Pathfinder, World of Darkness (Vampire), Call of Cthulu, Warhammer etc). I have a fair amount of experience with both 5E and Roll20 without being an expert on either.
I enjoy a casual type of game play with a good balance between role play, humor, puzzles and monster bashing. Generally it's all about having fun as a group, share some laughs and silly moments and experience the story together.
I like groups with a good synergy that works well together, more than groups with constant drama and infighting.
