Have you ever heard of a little game called Halo? In the multiplayer, it's just a bunch of Master Chiefs playing against each other. They could have made a multiplayer mode in which Samuses play against each other, but they didn't. And thats why Halo is a better game. BTW, it still is a first person shooter, not an adventure game, it makes no difference whether you keep your weapons or not. In adventure games like Tomb Raider, you don't get infinate ammo, but that doesn't make it an FPS.
