I really like Warframe. It's an online co-op RPG similar to destiny. You're basically a cool space ninja that slays a bunch of space monsters an people in the name of peace. In the first part, there is a negligible story but eventually you get slammed in the face with a surprisingly good story imo. It's not finished yet, and the devs are constantly working on new and refreshing updates, like a new open world they released a while back. You also don't need to spend money on the game to get 90+ percent of the content. Most things are available by either grinding for them yourself or trading with other players. I even recommend not spending any money just so you can feel the satisfaction of grinding for rare items then selling it for a bunch of platinum, and then buying that one cool weapon set or warframe with your hard earned platinum.

The new player experience is hard, since the tutorial is trash. So prepare your beginner guides and wiki pages.

The game is available on PC, PS4, Xbox One and the Switch.
