Gamepass is my rental service. It lets me try games I wouldn't have otherwise. I never considered ReCore for example, then for $1 I had a chance to give it a shot and ended up really enjoying the game, same thing for Super Lucky's Tale, We Happy Few, etc. I don't own the games, but I'm fine with that as any games I know I'll be going back to I will still be buying.
Gamepass is also helping me circumvent the EGS exclusives. When Outer Worlds releases I can play it on my PC through gamepass and if the modding community embraces the game like I'm hoping, after the 1 year exclusive deal is up I'll buy it on Steam just as the modding is kicking in and after all the major bugs have been fixed.
Fair use is a beautiful thing.
In the US you can alter anything you want to make a product you paid for continue to work. It's all included in fair use. If a game is currently on sale and being supported, you legally aren't allowed to distribute files that would circumvent their launcher without violating terms of use. It isn't illegal to alter the files on your own copy of the software though, that would only be a violation of terms. Violating terms of use isn't illegal, it only breaks the rules within that closed community and they are free to eject you from it which is what usually happens if you get caught. If you then decide to open your own server or distribute a modified version of the game while the game is being supported by the developer, legalities might ensue usually involving a C&D. Pressing your luck from there would just be stupid.
Link to court hearing involving altering a game's code to re-enable abandoned software. As things stand in the US, if a game has been discontinued or abandoned you are within your rights to alter it in a way that allows the game to continue to function. Whether this involves simply circumventing a launcher or creating a new server network to keep a multiplayer element going it is allowed, at least in the US. You are also allowed to distribute this alteration to others so that others may keep the game working. Profiting from distributing this altered software would not be covered under fair use and would be illegal however.
Federal rulings outweigh anything written on a box or manual by the manufacturer. Making copies of albums even for personal use is illegal according to every CD case I ever bought and the RIAA, but under fair use laws I am perfectly within my rights to do so as long as I am not distributing the copies. If the RIAA were to take me to court over it, it would be thrown out unless they could prove I was distributing the files.
Technically I'm not supposed to bypass Bethesda's launcher when I run a modded gamebryo engine game, but Bethesda updates break a lot of mods so I do it anyways. I doubt anyone would call that illegal. I bought the game, and I am legally allowed to do as I please with my property. As long as I don't try to sell the modified version of the game Bethesda doesn't care either. In fact many devs like Bethesda and Valve are completely open to modding with the devellopers/publisher's blessing.
