Oh, good news for you. They just released an update two days ago that separates the quests in the codex into story, side, and warframe quests. DE listened to player feedback and fixed the problem. Now you go to the codex terminal, you click on story quests, and it tells you what to do next.
Warframe is much more fun with friends. Friends will tell you that you don’t have to bother with all the currencies. You can just do the story missions.
Drag finished BOTW and now likes riding around Hyrule on a motorbike looking for koroks. Drag thinks the game is great if you use it as something to pick up and play a little bit of every now and then. Good game for bringing on airplanes and playing on the bus. Drag would have very much liked to have a game like that when drag was a child being dragged to boring dentist appointments and waiting to be picked up from school. Drag thinks maybe Nintendo is making games for children.
Drag can think of one counterexample: Warframe. But Warframe is also 100% free to play and free to participate in every content update and event. And Warframe is developed by an indie team from Fake London who started the game with 120 employees.
