Nope, all free... but if you really going to make a commercial game, better (really really should) use these icons here (and will be here) from now on since i'm going to make a BIG edit on all of them, most of these old icons are low in quality and poor in style (they're ruining my mind untill i eplace them all ).
Aside from icons my tileset, faces or characters whatever others are fine.
I have't quite gotten to use the icons (yet!) but I remember specially the plant tiles you made a long time ago. I've used them before (on a non commerical game) but are they avaliable for commerical too?
Tho it's awesome that we can use these icons already, holy **** look at those things @_@
Small rant: While using SRD Hud maker for a battle hud, I typed in the wrong script call and got an error, but then forgot to delete the piece that caused the error before closed the Hud maker and hit F5 to restart the game. Now everytime I engage in a battle my game crashes...
