User Rating: 9 | Warframe PC

I have been playing Warframe for over an year now. It pumps out amazing updates regularly and the game is constantly improving. The game has a massive learning curve, the tutorial isn't that polished, and you need to check wikis and guides constantly if you're a new player, for example, you open up the market and you will see a ton of weapons and gear ridiculous amount of money, what you don't see is the small section that sells you blueprints, and you can build weapons easily. The gameplay is extremely well done and the graphics are good for a F2P game.
