Ascended Fanon/I Knew It: The methods that have been constantly brought up by fans for common infantry to kill Jedi (actually using fully automatic fire, shotguns, shooting them with something bigger than small arms, abandoning Mook Chivalry) are the most effective way to kill the generic Jedi in campaign mode. Even these might not be enough, which is why there's the merry tactic of switching to a heavy trooper, taking out a landmine, and smacking the Jedi in the face with it.
Development Hell: Battlefront III went through quite a bit of this, in spite of both titles in the Battlefront series being the most financially successful Star Wars games made up until that point. Free Radical's Battlefront III was a mostly finished beta, but went unreleased after the developer working on it was bought out. Then LucasArts tried making a Tech Demo Game to lead into III... Which got cancelled once Disney bought Star Wars. LucasArts was then closed, seemingly ending the prospect of another Battlefront game. The Star Wars game rights were given to Electronic Arts, which left a lot of fans unhappy until they remembered that they own DICE, the company that made the Battlefield games upon which the Battlefront franchise is based. It was then announced at E3 2013 that the game (simply retitled Battlefront) was in production, with early gameplay footage revealed at E3 2014 and a release date set for 2015.
Sequel Gap: DICE's Battlefront, the first official installment in the series in years (not counting spin-offs), is slated to come out in November 2015 - a decade after the release of Battlefront II.
Streisand Effect: EA released an alpha for the 2015 game that was intended to be completely private. This backfired spectacularly when people uploaded footage of the game on various video websites, regardless of the NDA. More leaks popped up as soon as EA tried shutting existing leaks down. Luckily, the alpha was pretty solid, barring a few Good Bad Bugs.
