I forgot to save when I played Pokemon Ruby.
Like SO MANY TIMES. It was painful.

More recently I always forget to save in Fire Emblem: Awakening, before I started a battle.
I always get scared because in the last battle my character broke their sword so they can't attack and I totally forgot.
Then I fail.

I forgot on Yellow version like 3 times in a row lol, I had to go to sleep to make sure I didn't flip shit

Oh my gosh.
Sometimes I get Platinum Relics in Crash Warped
I
I forget to save.

I had Area 51?'s Platinum Relic once, and I forgot to save.

Now I make sure that I save at least three times after I get one.

Zelda games are the worst when you don't save them! Happened a bunch of times with Ocarina and Twilight Princess for me. I can never remember to save right before the final boss either so that when you finish it the game always returns to the last save point (which is usually near the start of the final dungeon or Ganon's Castle or whatever.) So that makes replaying the last boss all the more annoying.

My worst experience however was after finishing Wind Waker for the first time, it asked me where to save the new second quest to and I interpreted it as it asking me to save the game after I had finished it (and I was like FINALLY a Zelda game lets me save after I beat it!) Much tears were shed when I went back to the title screen and found out what I had just done to my save file I'd spent the last 3 years playing... It really killed my interest in playing the game again until Nintendo announced Wind Waker HD so I can replay it all again with it still being fresh.

I never forget to save.. If anything, I save too much..

Exactly what happened with my Skyward Sword file...

I've never had problems with forgetting to save, but ironically I restarted Pokemon Diamond and got all the way past the 1st gym only to realize I forgot to erase the previous file.-_-

Probably the worst thing of all is booting up a console to find all the save files on your memory card have suddenly vanished. Happened to me when I went to continue my current play through of Pokemon XD, it was so disheartening I didn't even feel like playing anymore.

Just beat a rather hard monster online in Monster Hunter Tri and got some rare materials... forgot to save.

There are a few games that the last save and the final boss fight are actually pretty far apart; which can be seriously annoying, was up until stupid o'clock in the morning finishing xenoblade.

I've never forgotten to save. Saved in the wrong place/wrong time? Definitely. Accidentally had the game lose power while saving? Yep. But I don't think I've ever forgotten to save after a long period of playing a game.

lmao i do this all the time. So many times i cant remember if i had just saved or not. Mind you this was about 2 seconds ago with no distractions.

Thats what sucks about Xenoblade.... SPOILERS

There is a huge amount of time after a certain point where you cant save. I left my Wii on for quite a while that day with a couple of breaks until i finally finished it off.

I've spent far too long with a Game Boy, or a DS, or something else running off batteries (in some of my older consoles prone to falling out), without nearby power source/spare batteries, to forget to save. It's pretty ingrained into me by this point.

New area ahead? Save.
Important battle? Save.
Defeated opponent in important battle? Save.
Made some progress? Save.
Potential for some unknown trap ahead? Save.
Pokémon center? Save.
Battery light red? Save. Save again to be sure.
Got momentarily distracted, not sure if just saved? Save again.
Battery light flashing? Save, and then

God forbid I lose the 20 minutes' progress since the last save

I've lately gone crazy and started saving things only when I absolutely have to. I self impose challenges like these on myself for no discernible reason, all the time.

Consequently, I've been having some trouble in games without checkpoints and autosaves, lately.

In Twilight Princess, I kept on getting to the Desert and beating it... then my brother gets the urge to start a new save file. Oh that's Dad's, don't delete that, Oooo! This one! 6 TIMES!

LOL epic pic

My Wii U froze on me while playing Darksiders 2.
I turned it back on and thankfully it auto saved.
I panicked for nothing

It's in grained in me doing the last 3

I rarely ever lose data due to not saving because I'm a compulsive saver. I save after every little thing actually.

"Omg I got a ruppee! SAAAAAVE"

"Holy crap a heart! SAAAAVE"

Okay maybe not to that extent but I still save way too much sometimes.

Figured out how to finally embed it lol
