I’m about 40 and have used them as demos for some time. There are a ton of games I’ve ended up buying that I never would’ve due to piracy. Maybe I’m all alone, but when finances are tight, I QUIT pirating games so I won’t find another I love.
Also I’m firmly in the “I bought it, so I should own it camp.” I have quite a few games that I’ll buy, but still use the pirated version because it doesn’t need the internet, or need to spend an hour updating every time I want to play.
