Gundato: They are divided into Favorites, Installed, and Not Installed. Alphabetical in each category. You can change that by the following:
Switch to the default display method (so not minimized)
You have tabs. Store, Community, My Games, etc.
Below that, you have "Games Status Gifts" etc. Click one of those. The arrow indicates if it is ascending or descending.
Yeah yeah, I know all that. Still, when you have a-hundred-and-fumpety games it can get messy. This time though the problem was more the fact hat I completely forgot about the not installed section, since I have so few games that are not installed. HL:Source was one of those few.
Anyway, you live and you learn. Will ponder SF4 for a while yet. I did play SF2 naturally, back in the day, but haven't played a fighting game since the days of SF2 and MK3. Back then I used to play hot seat with a friend or three, and it was a blast, but I was also 13 years old at the time.
I always saw fighting games as something simplistic, almost childish, with little replay value once you got the moves going. I'm probably completely wrong though and fighting games have evolved into the third and fourth coming by now.
Also, Osmos is feckin' hard, but strangely compelling.
