Non-nullable property 'Game' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Comparing an instance of System.Collections.Generic.List<EawModinfo.Spec.ILanguageInfo> with an instance of System.Collections.Generic.ISet<EawModinfo.Spec.ILanguageInfo> has undefined results, because the order of items in the set is not predictable. Create a stable order for the set (i.e., by using OrderBy from Linq). (https://xunit.net/xunit.analyzers/rules/xUnit2027)

Do not use Assert.Equal() to check for collection size. Use Assert.Single instead. (https://xunit.net/xunit.analyzers/rules/xUnit2013)
