I'm sort of both as a Viking Leader. So If I feel like brandishing my axe, I conquer. And if I'm not up for pillaging, I deal with diplomacy. Depends really on how I feel or upon the situation. There are no rules for a Viking!
I didn't really purchased anything from GOG yet. The two games in my library are just freebies. I'm broke now but for sure, I'll be buying CP2077 on GOG. But not if I won though. RIP support devs. I'm happy enough for just the game.
