There seem to be a lot of properties that are numeric or boolean, e.g.

    "base_happiness": 50,
    "capture_rate": 190,
    "forms_switchable": false,
    "gender_rate": 4,
    "has_gender_differences": true,
    "hatch_counter": 10,
    "is_baby": false,
    "is_legendary": false,
    "is_mythical": false,

Why not treat each of those properties as an extra dimension, and have the embedding model handle only the remaining (non-numeric) fields?

Is it because:

A) It's easier to just embed everything, or

B) Treating those numeric fields as separate dimensions would mean their interactions wouldn't be considered (without PCA), or

C) Something else?
