Secondly, this Eggman has learned from the mistakes of his past both E-102 Gamma and Chaos had betrayed him in Sonic Adventure.

Because he is seeking to discover and claim his grandfather's legacy, his mission is much more personal, so it makes sense for him to take to the field. Whereas Eggman in Sonic Adventure relied on his robots (and Chaos) to accomplish virtually all of his goals, this Eggman has multiple reasons not to do so.Having something to live up to motivates him to behave with greater dignity and self-respect, even if he still has the intemperance and impatience of his previous incarnation. Unlike the Eggman in Sonic Adventure, who was motivated only by egoism and megalomania, this Eggman has an idol in the form of his grandfather, whose legacy he has recently discovered and even respects.Arguably, this Eggman has matured as much as Tails has. Whereas Eggman in Sonic Adventure had many slapstick moments (including comical tantrums, crash landings in his Eggmobile, and getting stomped repeatedly by the heroes because he decides to fight them one-on-one), this Eggman is much more strategic, and is only ever humiliated in one very serious fight with Tails. This game's Eggman is markedly Darker and Edgier than the Eggman from the original Sonic Adventure, and is also far more proactive.
