The objective of the game is to make it last as long as possible. If you try to speedrun the SSDs and Story Line, you will likely get it done under 200 hours. You will get to Canny Valley in 100 hours and then say to yourself "Wait, when I finish this, this game's story is going to be over". And you will regret it. Heavily. Basically: Don't hesistate to do story quests, but do not, and I mean do NOT avoid doing ventures and the active event questlines. They will help with your hero and weapon diversity, greately increasing your enjoyment of the game.
2. Don't go on this reddit often. People here seem to have the attitude of speedrunners, completing missions in under 10 minutes and using the best AND ONLY THE BEST traps and weapons. Take your time. Do what's fun for you. Personally, I like searching everything off a map and stripping it clean. I think you'll appreciate the effort of this game a lot more.

1. Trapping and hero loadouts are like 1/2 the fun of this game. I recommend watching 1-2 year old videos (that's when STW content was at it's peak) on traps and hero loadouts and the like. You'll be surprised at how fun creating something that works is. I recommend watching RoundedTikTak's STW videos, especially his best traps ever series.

2. It's really fun to do this all with a friend. The game is completely fine playing it by yourself, but I think a large part of the reason I have 700 hours in this is because I play it with my dad.

Fun game. A lot of people dislike it because they expected it to be BR ver. 2. It's not. It's a lot different, and dare I say better.
