I bought this for $700 when it was on sale. It’s a complete game framework including extremely exciting features such as
- map and mini map
- interactibles
- character dialogues from audio files (works wits Metahumans)
- weapon and melee combat
- points of interests, quests and markers
- quest log
- motion matching
The vendor also does components of all these things, but the integrated version seemed the better option.
