Blopagol: Very! For a long time, so glad it finally got the release!
Blopagol: Me.
Solasta more focused on combat aspect implementation and feel of DnD5e, very true to it, but lighter on roleplaying and story.
Black Geyser more in the vein of Baldur's Gate with realtime with pause, so yeah more in the feel of a general immersion on role playing.
Hope this helps
