It depends what you consider finished.
Personally I haven't even beaten Oblivion's main quest line (or most of shivering isles), and I haven't even gotten into half of the Fallout 3 expansions, yet I consider both "done."
As games become larger, I find myself getting 100% completion on far fewer, and my standards for being finished become looser. I haven't beaten the omega weapons or any monster in the capture arena of FFX, yet I certainly don't look at that game box thinking "oh yeah, I need to get back to that."
In a shorter answer, for plenty of my games I have yet to finish the main storyline.
Especially PS2 games. Back then I couldn't often buy games, so I would buy them in waves (4-6 games at once). When I made the switch to PS3 I still had a couple games left to finish from my most recent purchase (along with some that I just hadn't managed to get all the way through). I ended up liking the HD visuals of the PS3 so much, that I couldn't go back to playing PS2 on my 13" CRT. I still have no idea how I managed to enjoy games on that tiny, low pixel-count, screen.
