Do you think that Konami gets together in a meeting, looks at the numbers, and says "Look, they play once twice per week, we can safely say that our F2P project is working and it's a success! Never mind that he didn't make any money from it." NO, Konami is losing people like me. I don't spend even the coins and points that Konami gives me away.
Konami and F2P games need as many active people as possible, that's why it's a FREE game, they people who play at least 2-3 hours every day, to get hooked to get started open packs. Of course, they have tools to monitor your every move! How often you log in, how much you play, what you play, who you play with, and how much you spend. Even if you and I stop playing.. not even once a week. even if all 100 or 1000 ppl that are coming here every day stop playing this crap, it will change nothing because there are millions out there on the phones or consoles, as I say they don't know better and for them, all that is normal.
Having worked in the Free2Play industry for a couple of years:
Yes a retention rate of 20 percent and having players come back to the game once or twice per week is considered a success and will also be presented as such in review meetings, so yes they will say: "look most players are at least playing or logging in twice a week, this is a success." Why?
Every time you log in and play an event or collect a daily reward is the potential of you turning into a payer or having an offer that gets you because of FOMO.
Of course they need active players but they also need players who are potential active players and payers meaning players like you. Those who still log in and play an event and might be with the right event or offer that you are more active again or that at least you play 2 online matches when you login so you already are part of the pool of the players they need for this day.
And saying nothing changes if you or I or 1000s of players stop playing, is exactly the reason why they don't have to change anything. Why don't you try it out. Don't login for a month. Or are you feeling you are missing out on their giveaway tokens and so on? If that is the reason then yes they got you and yes their mechanics work.
If 1000 players would churn and if players who are unhappy with the gameplay would stop playing then yes it would raise eyebrows.
Like you say they look at data. I know many people always think Free2Play companies only look at payers and while yes paying players are important, they often are also the most likely to churn and leave after a month or two. That is why having a good retention rate is so important. Also you need the free players as opponents.
And yes if suddenly there is a drop in Daily Active or monthly active users in any Free2Play company there would be concern. And again I said Daily Active users and not Daily paying users.
Sadly most people will always find an excuse, especially when they got hooked to a daily login mechanic: "if I quit nothing will change, a million other players play and so on"
This is exactly why Login bonuses have been introduced, they make people comfortable and they make them think others will still login. That is literally why it is called Fear Of Missing Out.
So again if you want changes and this is coming from someone who has worked on Free2Play in the past: stop playing. Drop in user numbers always gets attention.
And by the way: the biggest misconception is that free2play games need users who play 3 hours a day. They don't, most Free2Play games on the market plan that a player has 1 to 3 sessions of 5 to 20 minutes game time per session in a day depending on the game. Which is also another reason why offers work for example. People think others must play for hours so they buy an offer. Which is why usually events in Efootball give you a reward after one or two games. Now you have to stop a session because of family or job. So you get FOMO, since you might not get all the rewards that others are getting from the events, who have more time than you. And this in the end might make it more likely that you buy one of their offers.
Maybe if I have time someday I write down all the mechanics Efootball uses and what they target with each, if there is interest.
