The Game -- It Ain't Easy Being Rich & Famous (VIDEO)

The Game ... had a real moment with us Thursday night ... when he talked about the realities of being a celebrity.

Our photog spotted Game leaving Supperclub LA, and asked about the $12 million lawsuit filed by an off-duty cop who claims the rapper assaulted him during a basketball game.

Game made it clear ... he feels like a big target for people who want a payday, but at the same time he says it's his responsibility to contain himself.
