Lets be honest, TCGs became unplayable with the grwoing popularity of the Internet.
Before, you played Magic, you played YuGiOh, you played every game you liked, and every match you played had a new unique deck to play against, because noone knew the "I win" decks and everyone was using own decks
Honestly The Witcher 3 is the best RPG I've ever played. Definitely get the GOTY edition since it will be overall cheaper than buying all that content separately.
Honestly The Witcher 3 is great. Just go buy it. It was GOTY last year for a reason. 3 games everyone should have from last year is Witcher 3, Metal Gear Solid V and Bloodborne.
At any rate, Witcher 3 is one hell of a game either way, it blends the best characteristics of Western RPGs and Japanese RPGs. It's like the Racedriver GRID of RPGs. Game of the Decade easily, XD.
It's R$100 Jo, you'll get way more than your money's worth.
But have you played the other 2? They're not even close to 3 quality-wise, but the story is EXTREMELY linked between them, in fact there's a lot of quests that reference your actions in the first two games.
@Mooly Dooly Open Tvtropes, browse using the "Random Tropes" and/or the "Random Media" button, and when you come across a webcomic that sounds interessting to you, binge read it.
Alternatively, you could try nedroid.com
It's pretty good
