Do you actively seek out open source or commercial solutions to make game development easier? If so, where?
I usually search for opensource solutions on places like Sourceforge, and commercial ones from a number of graphics news websites, that link to the latest developments in tools.
If you were to use a third party solution, do you feel comfortable using open source or do you stick with a commercial product?
I'll stick with open source if things seem stable enough, but I usually go with commercial because things tend to be better developed.
If there were a site that featured solutions specifically for game development, would you like to see commercial solutions separate from OSS solutions?
Do you feel there is a need for a one-stop-shop for game development solutions?
If it was continually updated, and contained good information, yes.
