There's nothing else to do than being driven by the story^^
Sorry i didn't get your point. It's a game about tactical combat, if u just skip all dialogues you won't miss much. Same as if you read everything, you won't get much))
I read everything in Solasta and I get a story. It's not a complicated story, but it doesn't have to be. It's certainly enough to tie the pieces of the game together and give you some motivation to go around doing things. I wouldn't say it's about tactical combat, it just happens to do that really well and everything else is adequate.
