Game genres are so mixed these days that it is hard to find games that belong purely in just one genre... it also makes it hard to find interesting and unusual games to play (Sexy Brutale was great because of that). Words with Friends is about as far as my co-ordination skills will work on a mobile phone :p
I think Unreal Tournament was the beginning of the end for me when it comes to FPS...
I still managed with counterstrike and team fortress 2 until a few years ago. Finding a nice server with fun players is the key though. But even then, I get sick of doing the same thing over over over again...
Isn't Overwatch the one that all the cool kids are playing these days? Lots of games these days try to combine the action rpg/rts with fps elements. Not sure what is what these days...
Yes, I'm not cool...
I also find the online gaming community a bit toxic. If I only get a short time of quality gaming time. I'd rather not share it with a screaming teenager that is over sure of his gaming skills.
