For me it's Diablo II. Granted I've played my fair share of D2 since launch, and also recently on a private server with a comrade from hexbear, but I still feel like years later the game didn't grab me as much as D1 did.
Granted I don't hate D2, but for a game that I keep coming back to, D1 takes the prize.
Can you pirate the dlc "onto" a legitimate purchase or would i have to pirate everything?
i just nabbed everything but i believe it should work the way you describe as well. searching "cs.rin.ru sims 4" should take you where you need to go.
