I’ve seen the Purple Site and a few other do this time to time—have folks rank their Top 10 favorite RPGs as of right now. It gives a pretty good indicator of what the New Hotness is in some cases; in others, what folks skew towards on a certain site.
 
I have no idea how this would turn out for us, but people are list-crazy nowadays. So why don’t we give it a shot? Hell, I think I could list 20 favorites, but 10 will have to do for now (although I know I’m going to leave something out and be really mad later).
 
How it works: Rank your favorite RPGs right now from 1-10. A #1 ranking is worth 10 points, a #10 worth 1. Whenever the hell we feel like it, we tally it up and see what we have.

EDIT:  This is too tough.  Let's say you can also name 3 Honorable Mentions, for 1/2 point each.
 
So there we are. Let this completely meaningless, soon-to-be argument-prone exercise begin!

That's a really eclectic list, all quality stuff to be sure but very eclectic.

Alright...

1) Nemesis/Other uses of the ORE engine
2) BRP Call of Cthulhu
3) Cyberpunk 2020
4) Mekton Zeta Plus
5) FATE (waiting on the Dresden files "gritty" 3.0 version)
6) Werewolf: the Apocalypse
7) nWoD (as a mortals game)
d6 (which I have never played, but hear so much awesome about)
9) Ex Machina (for IOSHI, the most interesting and obfuscated non-setting I've ever seen - it would be rated higher if the spine of the book didn't stare at me accusingly until I break down and scream "What do I DO with you?!?!" at it)
10) RIFTS (for making a room full of engaged, employed, educated adults crack dirty jokes and blast NPCs with abandon like we were 13 again).

Honorable Mentions: AFMBE, Legend of the Five Rings, all versions of D&D.

I wanted to rate D&D higher, I really did. But I have an interesting relationship with the Most Popular Game of All Time - I love the play. I really do. Dungeons, dragons, gnolls, elves, Black Tentacles and Bigby's Fondlings and orbs of annihilation. I love pseudo-medieval euro-centric monster-stomp treasure-hunt adventure gaming - but it's never come with a system I've been happy with for more than about four sessions. They all get points for bringing D&D to me, but sometimes I wish D&D didn't use D&D's rules.

EDIT: I had to change the list around - I missed Mekton Zeta. So, ummm..that's the final.
