Okay, the Beach Bum pack added content to Singleplayer.
And I expect the Heist pack to do the same.
But ...Will they be fun?
I mean, really.
Can you pull a 1-3 man heist on the fly just like that? Or would that get boring/hard?
I can see how they'd work Online.
But I don't see how in Singleplayer.
And yes, I recall Rockstar saying Beach Bum, Content Creator and Heists were free packs.
