The key to playing an EA game is to not see yourself as someone who is buying a game. You are investing in a game you want to see completed, and in return you are basically granted access to a late alpha/early beta version of the game. The best way to handle it is to return after content updates whenever they occur and check out whats new. Or even let a few updates go by so when you come back you have a ton to do. Ive got a few EA games I do this with, Valheim is one of them, SCUM, Star Citizen. Baldurs Gate 3 as well but I only played that like a year ago and am waiting for full release now.

I dont think they will abandon it. Abandonware usually only happens with games that see very little success. Valheim made them like 100 million dollars. Only total stupidity, negligence and corruption would cause them to go bankrupt and have to abandon the game.

Now the VR scene... that has a TON of abandonware games that never took off and the devs stopped supporting.

TLDR; dont make an EA game your "main game" because you will be disappointed
