My RL friends stopped gaming years ago. I only play solo now when I do actually play. So, that doesn't become much of an issue for me lol. But, I do see your point if you establish online relationships with people how that could be a nuisance. Def not my case, but valid.
I do care about the aesthetics of a name. Hence why I used a capital G in my current name. I don't like to use y, p, j - I'm sure you get the point, unless its at the start or end of the name. Very specific on my own aesthetic expectations. I also dislike the use of numbers and prefer original names, etc.
Your name shows up everytime you chat, check scores, kill players, etc. So, it makes it very apparent. If you don't notice that, that's definitely a unique skill, lol. It's all personal preference, and I'm probably on the extreme side of aesthetically pleasing.
