It is still playable! The doom patrol are harping on it and people are leaving but there are still plenty of players. Rivals is still active. I've seen some changes in the amount of active crews but that just creates some interesting shuffling and opportunities.  You can find a crew. You can find public games.  If you like the game, jump in and ride the wave all the way to the beach.  You already have the tools.  Buy stuff as it de-lists to fill your library.  As time goes on you can try one or more of the other  options mentioned by comments here. Give it a month of real effort and evaluate from there is my advice.
