Tabletop RPGs are a great hobby, for me easily the best and more fun, period. Besides the stories, the battles, and the laughs, there is something that makes tabletop RPGs unique: they allow *everyone* to be creative. Not everyone is good at writing or playing music or painting, but *everyone* can play a role and have a lot of fun with it. RPGs are great for building solid friendships, or at least that was my case.
I certainly encourage everyone to go and try them, at least once.
I started playing MERP as my first RPG when I was 14, then for the following 6-7 years I played tons of different RPGs... actually I dare say I've played most of them at some point. I DM'ed rolemaster, Warhammer, Vampire and D&D, but as a player I tried many more games. Call of Cthuluh, Runequest, Stormbringer, Paranoia, Gamma World, Werewolf, Ars Magica, GURPS, Shadowrun, Cyberpunk... that is, nearly every game released before 1998. From then, I could only afford to play computer RPGs, but after a 20 year break my old group was reunited to play a D&D game and I am having a lot of fun as the DM.
The biggest challenge nowadays is, of course, finding a suitable group. Also, in the twitter era, many might find studying a 300 page manual a little disheartening. Yeah, being a DM takes work and it's not for everyone. The good news is modern systems like D&D 5e are easier than they look, and once you get the hang of the rules everything is rather natural. Players don't need to know the rules by heart, either.
