Should I get back into this game?

From what I remeber, have around 400+ hours in warframe but I left because of the shear lack of content. But with the new update I'm thinking about getting back into the game. Is it worth it?

I'd say wait till a week after August 25th, which is when Heart of Deimos launches, and then decide based on reviews.

I completely stopped playing Warframe. I played for over 3000 hours which is a lot. When I saw the new open world coming, I did not feel the excitement I had when I played the game so I decided quit. It is not because the game is bad, I just do not want to play it anymore.
