Why do people still drink Coke?There are so many new Tabletop RPGs out there that it's crazy to me people still play D&D after 45 years. It's certainly much more popular than a lot of the other RPGs that came out around the same time period. What is it about D&D that makes it stand out above the rest?
That's a bit unfair. D&D (especially if you're the DM, with another book to read) is work, sure. I can't imagine that learning Morrus's Simply 6 is work though, along with oodles of other rules-light games out there.Learning how an RPG system functions is work, therefore I only ever want to do it once; and as I've already done it there's no need to do it again.
I must be unusual in that I find reading a new RPG system to be fun, not work. I marvel at the new (to me) rules and itch to try them. I find learning an awesome new rules system to be very enjoyable.If work must be done I prefer to only have to do it once.
