Side quests are the way to go, the main campaign is not super rewarding

The worst part is that you’re forced to spend at least 1/3 of your time playing grinding out the main campaign. Then you are highly incentivised to spend another 1/3 of your time not playing due to the rest mechanic. That only leaves 1/3 of your time in game for any other tasks, including extra preparation for the main quest. Not to mention the fatigue system which often leaves you unable to do side quests when you have the opportunity.

I’m glad I didn’t get any of the classes with extra lives, to be honest.
