Gone are the days of the play to earn that they're all fun.
Yes the dramatic changes has made the game system not interesting any more as many game today has negligence on the fun but centered on the money gain, it's quite clear that fun alone can't make game interesting but the both side should be if balance for many don't go for game as fun but for money, but fun is also an attractive parts that making the game more interesting , the best us fun should be in balance with the money.
When your main motivation to play the game is to earn money, you'll lose the fun and eventually excitement will be gone.
That's what many and I have felt with those games that are ran by profit for gamers. But it's a dream for every gamer to earn while having fun, but the game itself is no longer fun.
When you focus on earning on the game, the main purpose of the game really changes and as a fun gamer, you'd feel that.
