too bad tweaker doesnt come with a warning like "hey this could permanently fuck your microsoft store install" because its an unstable software
Yeah, this concerns me too. I wish this whole login debacle was easier to deal with.
So just so we're clear here. When PSO2 first came out the MS had an issue where it would pretty much stop working, and people who have to spend the time they had getting permission to delete the files so they could re-install the game for it to seemly randomly happen again down the road (I don't think this happens anymore). This was an issue that a lot of people turned to the tweaker because (also lobby lag and stuff like that) - I was in the same boat where I didn't use the tweaker because the game worked fine for me until one day I spent like 4 hours trying to figure out why pso2 wouldn't work anymore.
Yeah this is the biggie, the game launched last year on PC in I believe the last week of May or so. Steam was announced and started the first update in August. I was about to give up on the game and I'm sure many actually did, but I know my install botched itself at least 6 times in that time period. This is also, one of the things that would have turned people onto tweaker very early on global.
This is a very lengthy process to fix too, you have to tell the MS store to uninstall. Then the backup files it shouldn't even make, have to be removed, which are located somewhere not accessible to regular users, and requires permissions voodoo to deal with. This however takes a ridiculous amount of time, especially if you're not installing it on an SSD, because Sega did some really bad file management on this game that I honestly hope they rebuild in NGS.
See, thing is, take Warframe for example, a similar style of f2p game, functionally, about the same age also. The game has a total of 188 files in my install, including some random files not everyone would have there. Meanwhile, a stock Sega PSO install, is over 100,000 files. Instead of packing many game assets into say an archive called "sound.dat" and "textures.dat" etc, it made every single file loose. So when the regular every day PC tools touch this, it has to recognize. Every. Single. File. Every one has to have a hash made and checked, every single file has to be moved or deleted when moving as well. In short, It'd take less time to move/modify a few large files, than a million small ones.
So basically, every time it botched this, you'd have to tell Windows to "uninstall." This didn't 'really' uninstall, it just moved the files to that backup area I mentioned earlier, but this involved touching every single file. Then, you'd have to get into that protected area I spoke of earlier, and delete them all, again, a process it does 100k times. Then, if it wasn't permanently deleted, and go sent to the recycle bin, well, you're effectively gonna be doing it another time.
After all that, you can then, reboot, and reinstall the game. Which then would grab an 11gb package from MS, then Sega's very slow patcher, would finish the rest. This is easily a multi hour process of thumb twiddling while it works. Mind you if it was on an SSD this could be faster probably at least 5 fold, but it's still not something anyone should have had to do. But yeah, they started updating the Steam version with Steam, recently, and then, Windows Store was supposedly supposed to follow so this issue may be gone.
I'm a bit concerned about tweaker for the promo stuff myself, actually. I wasn't able to get on the game today I keep getting a verison mismatch when I know very well that Steam updated this last night and no longer shows new updates. I will admit, that tweaker bypassing the patcher is nice, especially if the developer isn't truly using it anymore. However, I dunno if Sega put out another mini patch early today only on that, or what, but I can't even get on atm because of it.
I'd have rather not used tweaker but it's silly to have to have 100gb+ install of multiple copies of the game just to log in via another storefront. Honestly the Epic/Steam situation isn't prolly a big problem, but that windows store login method is a mess.
