Hmm I did get DDOS a couple times a VERY long time ago. Once noticeably against a guy in a cod zombies match who was making it very clear for me to be an hero and another random user took my side and he took that personally. Obviously trash talk is whatever in COD especially in MW2 and BO1 days, but that guy really gave me Zodiac vibes.
Obviously there is the annoying moments of host migration in COD games when you are just about to get a Nuke, ect. Getting betrayed right at the last second of Halo with a perfection. Many such cases.
Then there was Titanfall 1 dying. It became literally unplayable where one supposed hacker was able to shut down the ability to find a match (did they ever fix that?). I almost have to wonder if it was a Respawn conspiracy because Titanfall 1 didn't have any microtransactions and they were maybe losing money paying for the Microsoft cloud servers. Not even really joking. It's a bit sus that their games always have problems after they make a new one and they don't fix it. Similar thing happened when they were in charge of COD where the last COD would get hacked to death when the new one came out.
Below I brag a lot so I put in spoilers to be less annoying, people might not believe let alone care:
Then there are the xbox friends who I lost track of. Some of my friends just stopped gaming because of age and such or they took breaks, made new accounts, or I took breaks and forgot to keep up with them. I had a couple xbox friends who I also had added to facebook and skype, but I deleted my facebook after college.
Outside of multiplayer I've had a few technical issues with gaming in general. Although off topic these are additional worst gaming moments:
I had my original xbox 360 break and my Wii break. I had dropped my pokemon blue after collecting all 151 and resetting. Obviously I did not know about the battery inside games back then so I lost all my save data for other gen1/2 games as well over the years. It appears that with N64 only one of my games lost its save data (Mario Kart), but I know that's coming soon so I plan on just replacing them ASAP.
Recently I tried installing Sims 1 Complete Collection on iMac bootcamp Windows 10 and I think I screwed up. instead of trying to find solution online, I tried uninstalling and reinstalling. Problem is sims 1 has some weird glitch where its basically fused to system32 lol. This now makes fully uninstalling it impossible therefore reinstalling impossible.
