Then your hand has a lot more than 5 fingers, though^
Off the top of my head, the Mass Effect series (not sure if the first one, on PC it does come on two discs, but the other two do), Forza, Rage, Final Fantasy, Halo, Call of Duty, Battlefield... (yes, some counted here separate between SP and MP, but it's still valid, as they couldn't fit "the whole game" onto one disc, or they would have). And the ones counted are just the franchises, where sometimes several games have multiple discs.
Now, they surely don't make up the majority, but they aren't "niche games" either.
