I played Link's Crossbow Training and MOH Heroes 2 with the Wii Zapper - and I think it totally kicks ass. Sure it doesn't actually change how you play the game, but it definitely gives you a more authentic "light gun feel" when you play the games. If you're not going to get games like MOH Heroes 2, Link's Crossbow Training (which is packed in obviously), Resident Evil: the Umbrella Chronicles, Ghost Squad, and the upcoming House of the Dead games, then you have no reason to get one, but if you are into those games, then you owe it to yourself to buy a Wii Zapper. It's awesome. On a side note, if you have the Nyko Charge Station, which includes replacement battery covers/grips, then you need to remove the grips when you use the Wii Zapper, or it doesn't completely "lock" into place, which is only an issue when reloading in arcade mode in MOH.
