Some reference to the engine, such as the developer site or a wikipedia article.

The Sol engine is the in-house engine of Haemimont Games (https://en.wikipedia.org/wiki/Haemimont_Games). It has been in constant development since 2005, and has about 10 titles on Steam, with more on the way.


(Note: some of the older titles like Tzar and Rising Kingdoms are based on an earlier engine, not Sol)

Possible way to detect it

A folder called Packs/ contains multiple *.hpk files in it.
A folder called Local/ contains more *.hpk files, and all games so far have English.hpk (the default localization, English)

Is Local/English.hpk guaranteed to exist (from root folder)? If so, that's an easy detection.

It is guaranteed to exist in one of the depots, but not on every users' disk - e.g. if the user has chosen German language, they will only have German.hpk there.
