Unity Localization's Smart Strings (1.5.13) give dialogue lines pluralisation, gender, lists and conditionals with named placeholders; the documented trap is that sources are tried in order, so the same placeholder can resolve to different data, and number formatting follows the table's locale. Godot's tr_n plural support is for zero or positive integers only; its gettext extractor silently skips non-constant string arguments, and NO_TRANSLATE/TRANSLATORS comments steer extraction; pseudolocalisation catches length and hard-coded text but is not a CJK/RTL font test.
