I can't speak for everyone else and i don't know what the actual sales figures were like back then, but if i'm anything indicative of the average it's insane how much money lucasarts could have made if they just kept making shit.
A Bounty Hunter sequel where you're Boba Fett, hunting bounties across the galaxy during the Empire's height of power.
An Empire of War sequel (official, not modded) where you play as Thrawn and the reborn Emperor Palpatine during the Thrawn campaign and Operation Shadow Hand, as well as Admiral Ackbar during the Crimson Empire and Yuuzhan Vong War eras.
A Republic Commando sequel where you, as Sev, rescue your brothers from the Empire, and undertake missions from the early Rebel leaders like Bail Organa and Mon Mothma.
The next planned Rogue Squadron game, Dark Squadron, where you play as Darth Vader.
The next Jedi Knight game after Jedi Academy, which takes place during the Yuuzhan Vong invasion and the Second Galactic Civil War, where you fight the Vong, the rebuilt Empire, Lumiya, and Darth Caedus.
A KOTOR prequel set during the Mandalorian Wars, where you play as Revan and the Exile. Or a KOTOR sequel where you're Valkorion and you rule the Sith Empire, squash a rebellion by the Dark Council, kick Revan's ass, conquer Zakuul, and claim its throne for yourself.
A Force Unleashed III game that ties up everything nicely so that we get what happened to Starkiller, Juno, and Rahm Kota before EPIV.
Another Jedi action game similar to the EP3 game, except this time, it has all the Jedi and Sith characters from the movies, with missions and characters like Sidious training under Plagueis, Maul assassinating people for Sidious, or Luke fighting against Vader, TWICE.
The Battlefront III we were all waiting for.
A Jedi Starfighter game that takes place during the height of the Clone Wars.
Galactic Battlegrounds III: which includes all the faction in the films, with a comprehensive campaign spanning Episodes 1-VI, as well as more missions during the New Republic Era.
So many missed opportunities. So many things that could have been. So many things that slipped by us.
Hopefully, once Star Wars enters public domain, someone remembers to make these.........
