Sucker Punch's inFAMOUS has an unexpectedly earth-shattering "start" button. Literally. Other start sequences pale by comparison. They load looping feature demos or narrative clips that play like movie trailers without the thunder-throated Don LaFontaine voiceover. Not inFAMOUS. Its initial visual could be a webcam nestled somewhere in a city park at dusk. Street lamps glow serenely between gently rocking trees. Distant city buildings stand in reposeful silhouette. Even the electric billboards seem muted, pulsing reassuringly as off camera, children play and shout over composer Nathan Whitehead's mild, harp-touched orchestral pastiche.
