The supplied gameplay material shows the opening starter choice as Treecko, Torchic, or Mudkip. It does not provide a verified current-build ranking, base-stat comparison, or exclusive starter bonus, so those details are待确认.
GAMEPLAY SYSTEMS / emerald gamma pokemon starters
The three confirmed choices
The current available sources identify Treecko, Torchic, and Mudkip as the opening starter choices. This is the safe answer for the keyword because it comes from the collected gameplay material rather than an invented roster table.
The official page confirms the current route and battle systems, but the supplied document does not publish a starter tier list. Choose based on play preference until a version-tested comparison is available.
How to think about a choice
Gamma Emerald uses turn-based battles with abilities, held items, weather, status, and the physical/special split following Gen 6 rules. Those systems can affect how a team feels, but the available source materials do not give a complete matchup chart for the current Early Access route.
A starter guide can therefore explain the three options without claiming that one is objectively best. Exact early moves, encounter partners, and route efficiency are待确认 unless tested in the same version.
Build around the route
The available path runs from Littleroot Town through Mauville City and contains three gyms. Use Pokémon Center healing, PC storage, automatic HMs, and the day/night encounter system as the team develops.
The game also lists trainer rematches and a daycare, so a first choice does not have to carry every battle alone. Avoid publishing exact team recommendations until the current route roster is verified.
Historical notes stay historical
The old demo had its own island setting and should not be used as proof of the current starter balance. Historical changelog notes about starter saves and cutscenes belong to the old demo version.
