I just wondering about some legal stuff here.. is it okay if I use a very well known character/figure such as smiley/happy face in my commercial game ?? I don''t know if it licensed allready or not.. I hope not..

As always you need to talk to a lawyer, not a bunch of strangers on a forum who have no legal credentials.

Having said that I would venture to suggest that the smiley face is probably public domain. The image came out of the 60''s summer of love. Someone obviously came up with it first and they own the copyright but I expect they put it in the public domain as "ownership" wasn''t a big thing back then. Also they were probably so zonked on LSD that they don''t remember (hell they probably still don''t remember their own name).
