Mine was real content, concerning the title and its misleading implications. I'm sorry if you felt this was your magic moment to, ironically, sidetrack the thread if for but a moment just to shine your contemptuous little spotlight on me.
But let it not be said I never did anything for the people of OCR, obnoxiously officious though some of them may be ::haughty sip of tea::
I'm a bit like you, OP, where I do enjoy games that have the fun without the constraint of the global ending. Games like Unreal Tournament, any fighting game, and some puzzle games have that distinction. While they do have definitive goals "collect X McGuffans, kill Y enemies" these are only parameters.
I think it has something to do with narratives. If a game has a narrative, it must, by definition, have a global ending. Games without a narrative have no such restriction.
It might take some further research, but maybe you're just in the mood for a game without narrative bookends?
