the clone wars cartoon is canon but the makers have stated that the action is deliberately exaggerated only the events that happened within them are canon. the same with force unleashed the difference being the redirecting of the star destroyer wasnt an exaggerated game mechanic it was an event that furthered the plot and explained in the novel... whereas yodas plane crashing was eye candy. he canonically fought in the couracant battle but the fight itself was exaggerated...
