It would seem like I can't edit my old posts, so here is a new thread instead, so that I can put more games on the list. I also added the game Hero core.

For anyone interested in the old thread, it can be found here

that is am amazing list Fnord, good job ....there are quite a few ...you left off one of my suggestions..the Little Wizard, it is a lovely little java game by one guy who is quite talented, you have to explore a rather large map and cast spells, fight monsters and navigate a fun labyrinth....

http://www.thepcmanwebsite.com/media/little_wizard/

Thank you very much for collecting these, and for retrieving the thread, Fnord! ^_^

Here are a few suggestions of my own (alas, I'm away from my collection, and the AGS site seems to be down, so I'm likely forgetting a fair few :/):

Adventure:

• The Museum of Broken Memories
• Digital: A Love Story
• The Marionette

Interactive Fiction:

• Violet
• (At the IF Database (download, I think))
• (At Jay Is Games (played online, I believe))

Platformer:

•  A Game With a Kitty
• (The first game; I don't think that I've tried any of the later games.)

[edit] Bah, it seems that lists may be broken...

Darn it, I can't seem to edit the first post

There, I could edit the first post, and now everything seem to be in order

ah good there it is thanks.

Puzzle game:

Fool's Errand

http://www.thefoolandhismoney.com/01-the-fools-errand/index.htm

Adventure game (with lots of Myst references for fans):

Amertis

http://www.amertis.org/welcome.html

Thanks for your hard work, guys!  Very cool thread, thanks Fnord.

...so wasn't Broken Sword 2.5 (that recent indie/fanmade game) also for free?

Added Fool's Errand, Amertis & Broken Sword 2.5 to the list.

I also noticed that MechCommander 2 was not entirely free, just its source code, so I removed that game

Added one of the strangest games I've ever played to the list: Enviro Bear 2000: Operation hibernation.

Yes and I enjoyed playing 2.5..... Love B.S. games 

Added a whole slew of games: 

Renegade X: free rts game based on command & conquer with the unreal 3 engine

http://www.renegade-x.com/site/

Plenty of more games added, and now there is a sports category.

The website for Renegade X said that it is an FPS, so I'll add the game to that category. 

Huge update in almost all categories. 

Doom the rogue like just received a major update. It now has graphics by Derek Yu (of Aquaria fame)!
