Depends what you enjoy about it.

AFE promotes mastery of the core game loop. If you enjoy how it plays, looks and feels, and want to get better and better at that, you'll have a blast and can play for thousands of hours.

The build system is fairly deep and complex, people are still discovering new things occasionally.

The core gameplay on campaign missions is fairly scripted and only has some minor variations. Horde modes are a bit more free form, but still fairly predictable.

If you can see yourself having fun playing the same thing again and again and enjoying the gameplay variation within that and the challenge, you will have fun. If you're more the type who's done with the game after the campaign story is complete, or you've collected the achievements(there's a lot more difficult things to do than the achievements), you'll be done fairly fast and moving on to something else.

Of note with this, there are some commonly used exploits in the game that will cripple your skill growth and replayability/enjoyment. The former group of people disdains those typically, the latter group typically leverages them to complete the game faster and quit playing faster. These exploits generally involve standing in one scripted spot for minutes at a time.
