There's a good thread over on TBP about this. What happened or came out in 2008 that rocked your year?

Knights of the Old Republic Campaign Guide for Saga Edition

and

that's about it. It was a slow year for my game purchases I guess.

Edit: Ack - I thought it was just game releases the OP was talking about. Ahem. Well, my Star Wars Saga Edition series was great stuff (my players help make it so). We also had a good Prime Time Adventures series about Federal Time Cops. We had a good two-shot of Coyote Trail. We also had good one-shots of Shadowrun 4th Edition and D&D 4th Edition.

Finding an awesome game group for face to face gaming via this board.  Really, the best bunch of gamers I've come across in a long, long time.

Dragon Warriors and CthulhuTech were the stand out games of the year for me. Reign was a distant second, though it initially came out in 2007.

I enjoyed small forays into Dark Heresy and D&D4e but neither had much longevity.

One of the stand out products of this year was Thousand Thrones for WFRP.

Swords & Wizardry followed by OSRIC 2.0 and Mongoose Traveller.

D&D 4e
Carcosa
Random Esoteric Creature Generator
Dark Heresy

The campaigns I ran,

• Fourth Tiwesdæg - Dark Ages low fantasy using HarnMaster, a continuation of the adventures of the series. Played by Aron, Colin, Matt, and Kiwi Nick from 09Jan08-21Apr08.
  
• Just Speculatin' - scifi trade and adventure. scifi trade and adventure. Played 21Apr08-30Jun08, by Aron, Matt and Phill.
  
• Osere 2 - modern espionage, being played by Aron, Emil and Phill, 14Jul08-Oct08, 12 sessions
  

and one I played in,

• After World - A post-apocalyptic RPG using the All Flesh Must Be Eaten Rules, run by Matt in Melbourne by Dave, Mike and Kyle, 11 sessions from Oct07-Apr08.
  

-Two-Fisted Tales
-An awesome campaign that had a fantastic, open-door ending
-Fight On!
-Jamie Mal's Grognardia
-Getting to use Campaign Coins in my campaign
-Paizo's Pathfinder line
-Another kickass Gen Con
-Getting to tell Dave Arneson we had his seats ready at the ENnies; talking to him for a bit on the dealer room floor
-Seeing Col. Lou Zocchi again, introducing him to my daughter (he did magic tricks for her)
-A plethora of mighty fine simulacrum products
-Finding a few items for my Traveller collection

That's a good question. My year was definitely rocked, but not by any particular game or campaign.

Maybe it was sort of a critical accumulation of evidence of the obvious:
- People don't care what you played thirty years ago, but if you're playing Arduin, have an extra character, and are keeping it loose and fun, they might want to join.
- People don't care what the hot new game is, but if you're playing CthulhuTech, have an extra character, and are keeping it loose and fun, they might want to join.
- If you tell people they're going to play "Wizards and Lizards," and put that on their pregenerated character sheets, they have more fun than if you tell them they're going to play "RoleMaster."
- An flgs lives and dies on its culture, rather than merely its location.
- If you think you have some cool gaming idea, it's easier to do it and see what people think than it is to get people to think it's so cool that you ought to do it.
- Arrogant Bastard grows on you after a while. Celery is your friend. Lay off the cheese.

All this stuff is stuff I probably could have told you a long time ago, but this year has provided many pertinent and poignant anecdotes to convince me that I kinda know what I'm doing and I'm surrounded by some pretty cool people. That's a world-rocking realization.

* Kicking off Living Forgotten Realms!
* D&D4E is awesome
* Rediscovering AD&D1e
* producing a lot of music and for the first time in a while- art
* Getting divorced (no seriously, it turned out to be very awesome..)
* Moving to a new place that I love- I have a loft!
* lots of new gaming friends via LFR
* Another great GenCon- my 7th
* Lots of new neighbors
* Getting my scooter (2008 Honda Metropolitan- it rocks)
* finding a new girlfriend! (I swear this came months after I got divorced and moved out..!)
* Seeing a guy I taught how to play D&D in 2001 get extremely high praise as a DM on an unrelated yahoo group.

I had an immense amount of fun with Dark Heresy this year.

Mongoose Traveller and Sundered Skies

4e is good. I like it. I'm not head over heels, but..I like both Dark Heresy and CthulhuTech more than I thought I would. It's not a very original list, I know.

Hmmm... did the production version of Deluxe Basic Roleplaying come out in 2008, or late 2007?  I don't remember.  I know that I got my Advanced Reader's Copy late in 2007.

Anyway, I would say that it's probably Deluxe BRP and Hellas: Worlds of Sun and Stone.

I'm a Talislanta fan, and I like the Omni System.  Seeing something produced for the Omni System, and not by Morrigan Press (which is stagnant lately), is refreshing to say the least.  Also, not to mention that I like Greek Mythology and culture, and it has solar sail technology.

Cthulhutech and Dark Heresy as well as Left 4 Dead which while not an RPG supplement, it has firmly renewed my addiction to All Flesh Must Be Eaten.
