Rocks'n'Diamonds

If there are other (free) games with editors like this one that you make levels with list them here

Check out this topic:

There you can see some BD/RND-style games.

I'm creating a site with all quality boulderdash clones around with all available levelsets, music etc. Today I have finished the most important part of the Safrosoft RoX page.

Go here:

http://boulderdash.fateback.com/

I'm often working on it, so check it out regularly!

BTW this is about any game at all with level editors not just boulderdash style ones, example LaserTank

Well, it's quite logical of us to think you meant boulderdash games, because this is a boulderdash forum.
There are some good freeware games around. Some of them have level editors, others don't.
Here are some very good ones:

WITHOUT level editors:

Cho Ren Sha 68k - The best Japanese space shooter around. It gives you that old arcade feeling.

King's Quest I + II VGA - That old adventure game completely redrawn in VGA!
http://www.agdinteractive.com/

Quadra - The best tetris around with many extra's and possibility to play online.
http://quadra.sourceforge.net/

Zetrix - Another great Tetris game.

Pacventure - A great pacman game.

Games WITH level editors:

Frozen Bubble - A great Bust-a-move clone for many platforms.
http://www.frozen-bubble.org/

Mirror Magic - A Deflektor/Mindbender clone by Holger (also great but RnD rocks )
http://www.artsoft.org/mirrormagic/


But there are not so many games with level editors in comparison with games without, because it's no option for breakout/space shooter/adventure/pacman/tetris etc. games only for games which are different in each level, like Boulderdash games.
