Easily 30 or more.
So far I'm at 17 disc-based games. I've bought 2 new, and 15 used, 1 is PS3, 16 are PS2. Total I've spent on them is about $160. The 2 new ones are unopened and still shrink wrapped. Of the 15 used ones, 7 still haven't been inserted into my PS3 to test if they work. I've also bought 7 PSN titles, each at $5, for a total of $35 on digital download games so far.
What can I say, I enjoy buying video games.
EDIT: I also have this fear that one day, PS2 games will be impossible to find or outrageously priced, so I'm stocking up on anything even remotely interesting to me.
