What do you put in when a game asks you to write a name and why?

For sure SammoWammo! It's my default internet name.
And if that's taken, SammoDeWammo

unless its special, i just go with the main characters name. i like the story to match up

When I was little, I used to put my IRL name! But then, when I started making friends online and wanting to, for example, battle Pokemon with them, I realized I couldn't if I didn't want to expose my real name. I've always been an extremely privacy-conscious person, including from a young age, so from then on, I started using my online alias for my in-game names. I do this for most games now, not just games with online play!

For certain games, though, I use the character's canon name. This is in cases where the main character isn't intended to be as much of a self-insert as they are their own character. For example, in Undertale, Earthbound, and The Legend of Zelda, I use the main character's canon names. But for games like Pokemon, Fields of Mistria and Animal Crossing, I use my online alias.

usually I just put Zizi cuz Yep that's my name. however if i'm feeling a bit silly with it i may put something like "glorp" lol
the main exception is that historically, i've put some goofy variation on "link" for zelda games (like "lonk" "leenk" stuff like that). i also used to put the names of characters i was obsessed with into pokemon games for whatever reason but now i just put myself

It usually depends on what i'm doing and what playthrough i'm on! for example:

In deltarune, the game asks you for two names at the beginning of the game. One for you and one for your "vessel". During my first playthrough my instinct was to create a well thought out name for both me and my vessel. But, on subsequent playthroughs I've always used the names "Elv" and "Vessel" simply because I've discovered that it doesn't really matter!!! the game doesn't bring it up after you input it to say the least. Though i'm not really scared of spoiling an 8 year old game...

But! for Pokemon games, even if it doesn't matter on subsequent playthroughs I've always given my Pokemon a name, and given myself a cooler name! because in that case its more fun to pretend that i'm actually doing something. Sure, the game wont change because of my name and the names i give, but it lets me pretend that my Pokemon are all special!

tl;dr
For games where my name doesn't matter, i just default to a few options
For games where its more fun to have a name, i give cool names
