Since the topic is implied in a few other threads...

What games that you got in PDF have you run, and did you print out the game?

Mouse Guard: printed out a loaner copy for a friend; got it back. Ran a 6mo campaign with that printout, the PDF on my ebook reader, and a copy of the book.
Burning Empires: printed out only the Human Lifepaths, skill chapter, and trait chapter, plus the forms.
Buffy the Vampire Slayer: printed out only the Character Generation cheat sheet from the back and the character sheet; 9p total.
Mongoose Traveller: Playtest - yes, printed. Final: no; I've used it only for solo-play activities (T&C, Ship Building, Character Gen)
Mazes and Minotaurs: Yes, made nice 5x8 booklets!
Cyclopedia D&D: Ran a pickup session from PDF on laptop; have several hardcovers, tho...
T&T 7.5: have run sessions with only PDF available, but own dead tree
Traveller T20: Playtest - printed off 15 of 22 manuscripts. Use final manuscript draft; have never used my two comped hardcovers for actual play.
EABA: printed off EABA; never bothered printing STUFF.
Arrowflight: printed out PDFs, because I didn't have an ebook reader nor working laptop at the time. Still using that stack of comb-binds many years later.

There are a few others, but I can't remember the names right now, that I printed out.

Probably half what I run are games in development, and these are always pdf. The other games - my own finished games or others - are probably a third from pdf. Even when I run from a print book, I like having the pdf to print out character sheets and various sections for the players.

Only Coyote Trail.

I ended up printing it out eventually though. Does that count?

I ran a Labyrinth Lord game. It was an online pbp game. But I do have a print copy kicking around here at the house.

Star Cluster 2.5, Cold Space, Hard Nova, Cold Space, JAGs Wonderland, d4-d4, Spirit of the Century...and the list goes on and on. I have printed out a few pages of certain PDFs but that's it. I use my laptop at the game table and refer to it when necessary.

A few very short sessions of Swords & Wizardry with a visiting friend.

I use a BRP PDF on my girlfriend's laptop when we play our Beatrix Potter games, but I've got the hardcopy book there too.

This. Very much this.

If I am going to run a game that I got on PDF, I always have it printed.

I have not yet bought a PDF-only RPG, just PDF-only supplements and magazines.  All the PDF games that I have run have been freebies like Fudge, Mazes & Minotaurs, Swords & Wizardry, Labyrinth Lord, etc.

I'm not comfy running a game off pdf, I always get at least the sections I need printed out.  Or I peruse the free pdf then buy a hardcopy from Lulu, as with Mutant Future and Labyrinth Lord, both of which I've run successfully, and BFRPG - mostly to see what the coil binding was like!

Cold Space! The game so nice he mentions it twice!

Yeah - all those and The Terran Story too! And Creep Chronicles, and Shebang! The list goes ever on!

BASH- I printed out first.

FATE. One of the PCs printed and bound three copies b/c she worked at a copy shop.

I plan to run OpenQuest before the end of 2009, and that will be from a pdf.

Encounter Critical
Berin Kinsman's Bad Attitudes
Phillipe Tromeur's Wuthering Heights

I've run Kill Puppies For Satan from PDF. Fun game too.

Printed from PDF, I ran games of Arcana Unearthed and Iron Heroes that way.
I remember using the Ptolus PDFs directly during a game for quick reference, as well as chunks of the Veiled Society classic D&D module to cherry pick some components during the game.

Aside of that, I have a hard time remembering.
There must be other classic materials I printed out and used, but that doesn't come back to me right now.
