What I mean is how often people will talk about the game.
Just because people aren't talking about a game, doesn't mean it's not being played by people.
Look at Steam sales. When games get super low discounts, you can see heaps of people zurg rushing to buy and play the games they never got the chance to before.
Hell, I still play Sam & Max Hit the Road and many older games.
I won't be playing multiplayer in GTA V. I have no interest in multiplayer games, except splitscreen with my real life friends/siblings. I'm entirely getting this game for Single Player alone. That's why I don't give a stuff about Heists. Somehow I've managed to skip past all the spoilers so far.
