What's that particular thing that happens whenever you're playing your favorite video games that irks you so much? I know bugs can be one of them because it's what I hate most unless it's a game like Elder Scrolls where bugs are part of the game per say.
When it comes to being a gamer, the things I find frustrate me the most and that I hate are bugs, poor connection that causes lagging and also cheaters in online games.
I hate lag and server disconnection. I get frustrated when I experienced this each time I play games. I also dislike poor storytelling because that's what keep me engaged.
