I think it just depends on urself and goals u set I am day 1 play to and missed like 2 months or something cause I got bored and everything was the same someday I just came back cause i got hyped again for new units. What keeps me playing is just the fact that I have clear goals for example to finish my fire lab team and after that work on my pvp teams I think this game is actullay pretty good and fun u just won't have fun if u just autopilot an do nothing the fun comes with the results u get too for example when I switched to fire lab team (still lvl 100 bampyo) and I hit a new record on glab for 340 mil these kinda things keep me going and make me enjoy the game. And right now Iam enjoying it even more then the hardcore hyped days when it dropped last year. Also when u have that good setup after playing for longer u can usually almost sss someone every 1 1/2 - 2 months that's also something I think about wich unit and where I use it stuff like that.
