Dark souls 3 for a challenging hack and slash (although it gets easy if you master the timing for dodge/ parry / attack like monster hunter) and exploring ruins for secrets and the story of the world.

Witcher 3 for a story about adventure, sex, combat, the human nature, a bit of dark humor, siri and gwent. The expansion also gooding with full blown stories of theor own.

I haven't played DS2 in a long time, but if I'm not mistaken can avoid it first and fight later with better equipment.
