Steam says 143, plus gamemaker and Art Rage which go in the software tab, but a lot of the games it counts are just a series of separate applications for multi-player or specific game modes, so it's closer to 130 but with F2P games that I've played but uninstalled[and thus aren't shown in the game count] it's close to about 145.
I haven't played about 15 of them because I got them with the expectation of making my own pc, which is stuck in the phase of "I have chosen the parts, now just to get them" phase. Most of them I can't even play right now because the computer I used to use fried it's motherboard for the 2nd time about a month after the warranty expired, which coupled with the screen damage which was being worked around with an HDMI cable it's not worth the money to get it fixed, but until then I have to use a back-up computer that has a junk processor so I can barely play anything )=
