Why why why why why are you forcing us to use an EA app. Why can't we use both? It is seriously unstable. I have several EA games - for example three of them are Alice: Madness Returns, Sims 3, and Sims 4. I have EA Play on my Steam account. Sims 4 will play from Steam and EA including all packs and my custom content. Alice plays through Steam amd EA. (I have not tried any of the 12 other games I have through Origin.)
Now we come to Sims 3. It only shows up on EA app - not Steam. In the app it says I only own the base game and maybe one other expansion. If I run it from the EA App, I get the launcher info which says I own ALL the expansions/packs. BUT, the game won't start. I have tried the DX 9 install, no luck (I have Win11, i7-12700KF, NVidia 3080). So, I moved my old store-bought downloads out and into another folder and cleaned out the cache, downloads, worlds folders (my store bought worlds were missing anyway). I repaired the game through the EA app - still nothing.
So then I come across something about downloading Origin again. After doing so, it is FORCING me to upgrade to the useless EA app. We were told that the Origin app would still be available. We were told that you would patch the EA App so that Sims 3 would work - nothing works. I buy very few games through EA (12 in 20 years versus 250+ in Steam) because other than a few gems, they really are not that great. And the ones that are good are the old ones.
I want what you promised from the beginning - Origin continuing to work.
