Sorry for ignoring this for so long. I will finally review this next week. On first look these additions look reasonable. My bigger issue is with some of the Player implementations. Will write a longer text about them soon

You can mark it ready

Imo the major issue is stuff like this: https://github.com/rueter37/Player/commit/560fa522f0e7a1c6deeaeabb729d246f8c73ef6e

This is hard to read and lots of code-duplication. Will easily break when new stuff is added.

I guess the easiest way would be to add some new feature.cpp and feature.h that contains things like

namespace Feature {
    bool HasRpg2kBattleSystem();
    bool HasRpg2k3BattleSystem();
    bool HasRow();
    bool HasPlaceholders();
}

Similiar to the IsEngine stuff in Player.

HasPlacefolders could be e.g.

if (Player::IsRPG2kE()) {
    return true;
}

return Player::IsRPG2k3() && IsRpg2kBattleSystem() && lcf::Data::system.easyrpg_battle_use_rpg2ke_strings;

Maybe better when you also open a Player PR. Makes it easier to discuss it.

Added the feature namespace and opened a Player PR (Player#2697) now.
