I was like you at first. When I first saw Overwatch's promotionals I didn't plan to play it. Even though I played some FPS like Halo or Call of Duty, Overwatch seemed very difficult for me because I am not a very skilled player on that genre.
I mostly play RPG or adventure games. But once I decided to give it a try I haven't stopped playing. I play on PC and I am silver on rank and around level 513.
I've played a lot of Blizzard's game like Lost Vikings, Diablo, Starcraft and Warcraft.
