From my experience most of the stuff that uses steamworks for multiplayer can work on a pirated copy, you can only play with other pirates tho. Then games where you can host your own servers and p2p games can be done often as well. Some games that require you to use offical servers have server emus written for already but they arent finished iirc (i kbow of BO4 and Diablo3)
Prism needs a microsoft acc to work afaik, there probably is a fork that doesnt but i dont know of. All my recommendations came from either the megathread here or fmhy.net
From my experience yes, most releases include German and English often with subs. I prefer English dubs over german ones most of the time but a lot of family members want the German ones so I look out for releases that include both. Try and look for a "DL" before the source, like Movie.Year.German.DL.WEB-DL....
Prowlarr has some listed and once you are in some of the ones with more aktive forums you can find a some more. But i agree it is a lot harder to find german ones.
WOT, TFA, ST-Tracker, Torrent-explosive, immortous are some good ones but they are provate. There arent really any public sites but getting into the private ones isnt hard. I might be able to send you an invite to one or two ot them if i have any, shoot me a dm if you want one.
It is, you just gotta find the right sources. Im on multiple trackers that focus on german dubs and can get most of the stuff i want. Everything else is just a request away.
maybe try koalageddon, it can hook into the steam client itself and unlock them from there. if the game doesnt ship the files for the dlcs with the game unless you have bought the dlc then you can probably find them in the games thread on cs.rin.ru
DRM free games dont need steam emus, they have no DRM just copy and paste the files and your good to go. Almost all other games that only use Steam's DRM can be cracked by replacing the dll and in some cases patching the exe. There are tools that to all the heavy lifting for you.
If you are using jackett or prowlarr then filter the indexers by language and only select the german ones and try to get into them. Some will let you fill out a form to get an invite
For those looking to download it to play with friends, there is no console so you cant connect to anyone and for zombies only firebase z works. Get MW2019 instead there you can at least play multiplayer together
i dont think thats the offical site for dodi repacks, fmhy and the megathread here both point to dodi-repacks.site
