First game I ever played on PC was team fortress(2008) then i started watching SFM's and shit like that.. I saw someone that made a tutorial like how to make a SFM and he did it in gmod.. so gmod is my second game i ever played on steam(2008), then Minecraft on 2011 loool(also ray-man PS2, tekken ps2, gta vice city and gta san andreas on PS2) (also css, 1.6, hl2e2 and portal 2 xdddd forgot to metion them)
Reason for playing on PC when I was that young was because I went to Israel with my family when I was 6 years old and I had no friends in school because I didn't speak Hebrew(the main language in Israel), so I had to play PC or sum like that.
