I did see young people play D&D on their own. I came home on day with my 6, 7, and 8 year old cousins sprawled on my living room floor with my 4e core books screaming "Twin Strike!" The 6 your DMing by reading the many 4e charts for everything.
Because everyone learns differently. My baby cousins understand colors and charts and got Green powers, Red Powers, and Black Powers, that Brute are melee with low AC and high HP, and the DC for level 1 were.
But the part that I was stressing is that 4e Essentials is not the same as 4e Original and Natural Language is not a substitute for clear information.
Allof the 5e accessibility was excellent. However the "You can change up things at your table" and "You DMcan alter things" ideas were serverely hampered because theguts of the systemwere not clearly explained. It was a community effort of breaking down 5e and getting it to shift to different styles of play like sword andsorcery,epic fantasy, hardcore tactics, silly roleplay, etc. The community covered 5e's butt when people grew experience and wanted to tailor the game to their preferences.
