Exaggerated: In Legends of Telebrion, the Troperia ending is boring and difficult to play through, leading to nobody playing it, but La Résistance ends up doing a couple of morally grey things. Legends of Telebrion II establishes that he joined Troperia almost immediately.
Downplayed: In Legends of Telebrion you can take any ending you want. In the sequel, it's ambiguous what faction Bob chose, but it's clear he never took over rule of Troperia, he talked Emperor Evulz down from the path of genocide, and that he stopped La Résistance from destroying a city suspected of holding Evulz's agents.
Legends of Telebrion II reveals that Bob canonically chose to side with the empire.
Legends of Telebrion II picks up from good endings, but it's later revealed that the new villain is none other than Bob from an Alternate Universe who joined Evulz' empire. So both endings are canon in a way.
Double Subverted: Legends of Telebrion IIappears to have had Bob join the empire... however, this is later revealed to be propaganda spread by Evulz; Bob actually joined one of the other factions, but it's not clarified which.
Legends of Telebrion II is decidedly set after Bob sided with the good kingdom, locking out the other possible endings. However, it delves into the results of this decision in such a way that it eventually becomes clear that the seemingly Lawful Good kingdom wasn't so wonderful after all and is basically Lawful Neutral now, which has had many negative effects on the world. It's hinted that the world would have been better off in some ways if one of the other factions won — but worse in others.
Legends of Telebrion is a long-running series; some games have a "good" canonical ending while others use a "bad" ending as canon.
The "official" storyline is The Kingdom and La Résistance wins, but the first DLC pack (bundled with the pre-order and released on it's own a month after the game's release) is a campaign for The Empire.
Related to the above, the game company makes two versions of the second game, one in which the good guys won in the first game, the other in which the bad guys won.
Legends of Telebrion doesn't have a sequel, or the sequel is non linear.
All three endings to Legends of Telebrion end with the world in a roughly same state, since most of the differences between the campaigns affect only the characters and relationships between them. Legends of Telebrion II follows a new set of characters and makes few enough references to the first game that any three endings could be possible.
Legends of Telebrion II uses an Old Save Bonus to let the player continue with their previous alignment.
Enforced: The Evil endings usually involve destroying the world or some sort of other, very final, conclusion. The Good endings leave a lot more room for sequels. If the creators want to make money, they'd better pick the Good endings.
Invoked: The Fourth Wall Observer party member tries to talk down Bob from turning to the dark side, telling him he'll still end up on the light side in the sequel.
Defied: Legends of Telebrion II features three separate campaigns, each of which assumes a different ending of the first game was canon.
Deconstructed: Legends of Telebrion II starts off with an ambiguous good ending having occurred, such that the evil ending couldn't have happened. You later find out that none of the three endings could have happened - in canon, Bob died in battle, his actions having absolutely no impact on the world whatsoever, just as the players' choice had none.
Reconstructed: However, Bob becomes a good and decent hero and is able to choose between the good factions, was inspired to strive for his noble goals by hearing of the struggles and sacrifices which could only be possible if the good ending happened.
Played For Drama: In Legends of Telebrion II, Bob is a loyal knight of The Kingdom of Troperia, in accordance with the good ending of the first game. As the game continues, it comes to light that he used to be The Dragon to Emperor Evulz, which is what he was in the bad ending of the first game. Then the Kingdom of Troperia captured him and wiped his mind. And the mind wipe is starting to wear off...
