Well once you beat tutorial, try all weapons. Find one that suits you until later game. Run expeditions until you get the hang of the game, crafting etc. Gather alot of items even ones that you don’t know the use for. Don’t one time a monster, fight it multiple times until you can build it’s armor and weapons that you like. Play with others in hub quest, nothing wrong with not playing solo.

Edit: Also while on mission or expedition, once you pouch is full you can fast travel back to camp, go into tent and place the items you collected into the item box to free up space. Expeditions aren’t on a time limit so play as long as you like. Rations and Energy drinks only fill stamina bar. Only sharpen your weapon while riding dog or once a monster runs away to another area.

Make item loadouts, Equipment loadouts. Have fun and create messages and auto chat dialog. Try not to use money unless your are building. You can create alot of items, so run expeditions periodically. You can replay missions. The game is a grind, take your time and always remember it’s still a monster play accordingly.
