So given that this is an FE forum and FE is a video game, I'm guessing most people here have at least one interesting video game memories or some special "OMG moment". Thought it'd be cool to share them.
My absolute favorite video game memory involves Megaman Battle Network 2 for the GBA. To start you should know that in this game, you can pick "battle chips", that are basically super attacks, at the beginning of each fight, and again once a certain bar fills.
This was the first videogame I owned, and I had just moved to the US. Naturally the game was in english, and I had no idea what was going on, so during the tutorial I never got that you could pick battle chips again. So I played the entire game up until the last boss with just the initial Chips and the Megabuster (which is very weak in this game) until in on the last boss. During the final boss fight (when I had a better grasp on english), I noticed that on the little bar that let's you know when you can pick chips again there was a text that said "Press R or L". I did so and I realized that I could PICK CHIPS AGAIN! I went on to destroy the final boss and it felt AWESOME.
