Im playing pathfinder and have the pathfinder 2 playtest books and might play 5e someday soon.
@Codex404 5e, haven't played any other version so I don't know the difference that well.
@martijnimhoff 5e is nore storytelling and simpler mechanics. In 3e it was way more difficult to work through things.
5e is super intuitive and puts the focus on the story/roleplaying, if I'm ever DMing for new players I'll use it. However, some of my more advanced groups feel 3.5 is better for actual raw game mechanics.
