Walkthrough

Adds Hawaii as a new map: data and manifest files, registers it in the map generator and playlist, exposes it in game map types, updates English localization, and adds credits entries.

Poem

Aloha, nine isles now in the repo,
Small JSON shores where new pixels go,
Enum, playlist, locale sing along,
Credits and manifest hum the song,
Waves of code — a quiet, bright hello. 🌺

44-48: Kahoolawe is a very small island — is it a fun nation to play?

Kahoolawe is tiny compared to the other islands. If it ends up with very few land tiles, it might feel unbalanced or not enjoyable as a playable nation. Since you playtested this, you probably already know — just double-checking it feels right in-game.

I'm not sure at all but this map might be too big?
Someone on the main discord said that the only map which lags for them is japan (2500x2500, 488k land tiles).

[Duwibi]

Simular to Flo, I also think the map would be too big to be able to be queued for public lobbies. With that size, it would probably lag on PC, let alone on lower-end phones and tablets. How did your own testing go?
The other thing I wanna ask is what base map did you use? (It needs to have copyright rules which allow for commercial use).
Overall, if the base map isn't under strict copyright and it runns somewhat smoothly, we could add it to the game to be played in singleplayer and private lobbies. But it's definitely too big for public lobbies imo 🤔

I played a few solo matches on this map with no issues, though it was on a M4 MBA. I increased the size because it felt a bit cramped when it was Faroe-Island-map-sized-ish, but happy to scale it down.

Done

[gabigabogabu]

Scaled down the map from 3920x2544 (612K land tiles) to 3200x2076 (408K land tiles)

[Duwibi]

I think it's ok for now. If it causes performence issues during the playtest, we can always remove it from public lobbies :)

Thanks!
