My suggestion is: if you plan on using any Moto Mods, go without a case or just a simple bumper case. If you have no intention of using Moto Mods get a thin case that adds a little "grip". You either need a Style Shell Mod or case to protect the back of the phone and the Moto Mod pins. I don't think anyone makes a case that fits over a Style Shell. So it's either no Moto Mods / Style Shell attached & a case. Or Style Shell & Moto Mods without a case, or bumper case.
As far as screen protectors, I haven't used one on a Gorilla Glass screen in years. In my opinion modern Gorilla Glass is very scratch resistant and doesn't need a screen protector. That's just my opinion though, I know many people use them on Gorilla Glass. Shattershield screens absolutely need a screen protector, but the Z2 Play is not Shattershield, it's traditional Gorilla Glass.
