I tried now somethings with ags, and its really good, but I have this question...
I'm making an adventure with 3D movement... and I'm TRYING to make it good enough to sell. Should you recomment me working in Adventuremaker. or with AGS? Are the features of Adventuremaker worth $99 considered to the free AGS?
AGS is capable of making very professional games,
look at kq2vga for example....
anyways,
I don't know adventuremaker, so I don't know, if it supports 3d better then ags then probably, yes....
but AGS r0x any game studio so far
why do you want to sell it, why not make a free game?
Depends on what kind of person you are:
If paying $99 or a certain amount of money motivates you to use that product whereas you take it for granted when its free- by all means pay up.
Otherwise, to answer your question: No.
