<P> The influence of younger dramatists such as John Marston and Ben Jonson is seen not only in the problem plays, which dramatise intractable human problems of greed and lust, but also in the darker tone of the Jacobean tragedies . The Marlovian, heroic mode of the Elizabethan tragedies is gone, replaced by a darker vision of heroic natures caught in environments of pervasive corruption . As a sharer in both the Globe and in the King's Men, Shakespeare never wrote for the boys' companies; however, his early Jacobean work is markedly influenced by the techniques of the new, satiric dramatists . One play, Troilus and Cressida, may even have been inspired by the War of the Theatres . </P> <P> Shakespeare's final plays hark back to his Elizabethan comedies in their use of romantic situation and incident . In these plays, however, the sombre elements that are largely glossed over in the earlier plays are brought to the fore and often rendered dramatically vivid . This change is related to the success of tragicomedies such as Philaster, although the uncertainty of dates makes the nature and direction of the influence unclear . From the evidence of the title - page to The Two Noble Kinsmen and from textual analysis it is believed by some editors that Shakespeare ended his career in collaboration with Fletcher, who succeeded him as house playwright for the King's Men . These last plays resemble Fletcher's tragicomedies in their attempt to find a comedic mode capable of dramatising more serious events than had his earlier comedies . </P> <P> During the reign of Queen Elizabeth, "drama became the ideal means to capture and convey the diverse interests of the time ." Stories of various genres were enacted for audiences consisting of both the wealthy and educated and the poor and illiterate . Later on, he retired at the height of the Jacobean period, not long before the start of the Thirty Years' War . His verse style, his choice of subjects, and his stagecraft all bear the marks of both periods . His style changed not only in accordance with his own tastes and developing mastery, but also in accord with the tastes of the audiences for whom he wrote . </P> <P> While many passages in Shakespeare's plays are written in prose, he almost always wrote a large proportion of his plays and poems in iambic pentameter . In some of his early works (like Romeo and Juliet), he even added punctuation at the end of these iambic pentameter lines to make the rhythm even stronger . He and many dramatists of this period used the form of blank verse extensively in character dialogue, thus heightening poetic effects . </P>
