If you learned to play Dungeons & Dragons back in 1983 or thereabouts you may well have done so with the D&D Basic Set, a red box that included a solo choose-your-own-adventure to introduce the basics of the Basic rules. That adventure's star NPCs, Aleena the cleric and Bargle the Infamous, are still fondly remembered (and hated, in Bargle's case) by an entire generation of roleplayers today.
Wizards of the Coast has created a new pick-a-path introduction to D&D called Before the Storm, no relation to the Life is Strange prequel, which you can play in a browser. You get to select a character from five options—human paladin, hill dwarf cleric, lightfoot halfling rogue, high elf wizard, or wood elf fighter—and play through a story that introduces the rules of D&D's 5th edition.
