I don't have a exact count since I got games in several boxes around here. But I'm guessing I have probably 100-150 or so. Alot of which were big hits on Windows/Dos at one point or another in the past 15 years.
Same here. Maybe about 50-60 momentarily. Used to be many more, since it has been a long time now that I play games. But I have them stuffed away, some got stolen already or I gave 'em away.
Fact is, its not even a hand full anymore I have installed on my boxes and only one Linux game (Eschalon: Book I). I'm not much of a gamer anymore. They lost most of their attraction they once had to me and I don't enjoy playing game anymore like I did years back.
