B/X is "Basic/Expert D&D", one of the D&D versions published in the early 80s. G+ is Google Plus, a website that had a really active RPG community. I'm interested in Lamentations of the Flame Princess, Call of Cthulhu, D&D any edition, Shadows of the Demon Lord, Vampire, Dungeon Crawl Classics, Starfinder, Pathfinder, Warhammer Fantasy Roleplay, Zweihander... WOTC is Wizards of the Coast. HotDQ is Hoard of the Dragon Queen, a WOTC module. ToA is Tomb of Annihilation, a WOTC module. SKT is Storm King's Thunder, a WOTC module. Edit: Your profile says you played "white box D&D". B/X is Moldvay D&D in the magenta box. It's one of the foundations of the "OSR" (old school revival) movements in RPGs that lead to a lot of great products. Check it out, you may be missing out on some really good stuff.
