I'm honestly not really all that good with video games. I just tend to obsess over the few that I actually like and sometimes I play them enough times to become at least above average at them. For most games though, I just either never can get them or plain just can never get into them.
I'm really bad at sports games like FIFA, for example, mostly because I'm not that interested in sports to begin with and I'm even more disinterested in their video game versions, so I just ultimately never got to be good at any of them, including NBA and other similar sports video games. Also I'm not very good at FPS, to be honest. I always end up being the most killed, though I guess I would probably get better at it if I obsessed over it like most of my friends do.
Which games are you the worst at?
