This happened to me the other day. I've had FarCry4 on my Xbox for years. Never played it. Well the other day, started playing it. Died A LOT. But was still having a blast, visuals are a little dated, but the atmosphere and game mechanics are still very fun overall.
Haven't dived deep yet into the FarCry4 story/lore, but hoping it picks up more. But as I was dying a lot. I wasn't having any fun. So I stopped playing it for a couple days, and came back to it, fully refreshed and fully restored to tackle the mission. Spoiler: the fun stayed :)
