Because those are mutally exclusive
At long last, Sony has delivered a solid month for PlayStation Plus subscribers. After last month’s kerfuffle with removing PES 2019 for the “classic” that is Detroit: Become Human, there really isn’t much reason to complain about August’s options. Both Sniper Elite 4 and Wipeout Omega Collection are worth playing and should occupy even the most discerning of players.
While I don’t see the common thread here, you’re bound to get some fun out of either title. The current selection will be removed after August 5, so you still have another week to grab last month’s options. I’d say don’t miss out on Detroit, but I don’t want to lie to anyone.
