Gangster Town, hands down. The other SMS phaser games are alright, but nothing comes close to Gangster Town. That game alone is worth picking up a phaser. also, I think the phaser is just cooler looking than the zapper and the trigger is much better as well. I want to track down a spare preferrably non-working phaser and gut it, replacing it with the parts of an NES zapper. a zapper in a phaser shell would be awesome. but that's just me.
