>>12817251Start with Witcher 3. It's easy to jump into the story. It's unironically one of the greatest games ever made. It really feels like a game almost completely made for 4chan chuds. The story is good, your decisions matter, exploring is fun and rewarding, all of the females are HOT and you CAN have sex with them.
Chances are after that you're going to be hooked and want more. The 2nd game is good albeit not as good as 3. The first game has not aged well and is currently being remade so just wait on that. The books are actually collections of short stories and they're hit or miss for me, but chances are if you like the game enough you'll get some sort of enjoyment from it. The tv show is not good in any way really.
