I think the problem you had with the Smurfs copyright holders is that you didn't ask for permission.
Why not get permission to use a franchise in your games? Then you won't have any problems.
If they won't give you permission, then maybe you should come up with your own characters.
Reading your posts, I don't like the sound of your attitude, Hippoonios.
You sound to me like you make your own bad luck. I think they were right to sue. Who'd want to deal with a foul mouthed 'blame the world instead' type of guy like you?
'lamer' indeed. Pathetic.
