30 seems to be the maximum number of games you can run at once that will actually get recorded by Steam.

Ok then , thanks for the answer , i've actually noticed that it auto-updates so that when a game hits 2 hrs it automatically gives its place to another one that needs to reach the 2hrs mark... very nice

i am currently running idlemaster and steam achievement manager to exceed more then 30 at a time, just to get the 2 hour mark on them faster. i have IM going alphabetical and starting from Z on SAM and working backwards with another 30. seems to be working great for me sp far. like you i also have tons of games that i want to get my cards from. it's worth a shot, except with SAM you have to change them every 2hrs, it won't cut off when it hits the 2 hour mark. so it's a little more complicated then IM.
