A particular standout for animation is Rolling Thunder. True, thereís little to do but duck, jump, and shoot. But I look at how smooth the animation is when the character swings over the banister to the upper floor and itís hard not to appreciate the work that went into it.
As for music, most of these games have a way with catchy tunes. SkyKid has a jaunty tune that makes it sound like youíre already taking part in your military victory parade. Galaga doesnít have much for music, but the theme that plays when you warp to the next battle always gets me amped up. Dig Dug probably makes the most creative use of sound, as the music only plays when you move.
And, of course, if youíve come for sound effects, these games will give you your retro fill. They run the spectrum from the Pac-Man "wakka wakka," the sometimes eerie sounds of space bugs in Galaga, to the charming "pew pew" sounds from all the rest of the shooters in this collection.
