I wonder what's their plan.
Going by last couple of years - Konami is not very creative and lack imagination. Their content, if you can call it that, was almost non existent. Going F2P means that they would really need to up their game.
People rarely get attached to F2P games.
My every adventure with F2P games was very brief - download, try, uninstall.
If they think that people will stay with them for longer just because its F2P - they are in for a shock. You need huge support and huge content to keep people entertained.
Look at GTA Online and RdR2 Online. GTA has plenty of support, constant updates, events. And it has player base.
RdR2 is no doubt better game. Realistic, immersive, with core mechanics that blow GTA out of the water.
But it has fuck all support. So it has fuck all players in compare to GTA.
I know there are games out there, like Fortnite, that has huge player base, but my blood boils when pesuniverse are bringing up Fortnite, when talking about eFootball, as a possible measure of success (Fortnite is also cross platform and scaled depending of the device played)
But Fortnite is a game for kids. Its an insult for anyone who wants to play immersive and realistic shooter.
So if eFootball direction is similar to Fortnite - its actually a fucking nightmare come true.
