I like to think that Jijimon watched his house and whole city transform while the kid he brought to save the island ran around completely ignoring him for months.
A couple fun facts about breaking the sequence this way-
After recruiting Penguinmon you are completely locked out of curling.
The last thing Myotismon says after completing the Mansion questline is that he will meet you at the Arena (that doesn't exist)
These are the only ones that won't join the city until the Arena has been built-
Gekomon (joins the arena)
Kabuterimon (dialog options won't appear until there is an Arena in town)
Andromon (same as Kabuterimon)
and in turn, Giromon.
Greymon (Triggered by talking to Jijimon)
Airdramon (won't show up until the second interaction with Jijimon and the Greymon event is triggered first)
Then, the rest of the digimon are locked behind Mount Infinity.
Devimon
Megadramon
Metal Greymon
Digitamamon
I really adore this game and just wanted to see how far I could get playing through it in a weird way.
