The thesaurus isn't giving me any workable synonyms for 'epic,' and thank god, because I can't think of a single word that defines the newest "God of War III (PS3)" trailer better :
When I encountered the 'brain made of dead people' boss in "Castlevania: Symphony of the Night," or the 'giant butthole monster' in "Dead Space," I thought I had reached the limits of larger-than-life battles, but apparently I was sorely mistaken. After all, I wasn't wearing gigantic lion-head gauntlets and punching a giant cyclops on the back of a Titan climbing mount Olympus. Kinda makes real life seem drab, doesn't it?
