Hmm. That's odd. I thought I wrote a post about this last night. Now I can't find it. Well, it was very late ...
Anyway, I'm with Roland and Victoria that the ILE threads are of a different nature than the games threads. They're not wordplay or puzzles, they're about expressing potentially more profound thoughts and emotions. (Sometimes the games elicit profundity, too, but that's not their primary purpose. And sometimes the ILE posts are funny or flippant, but they're also meant to allow for seriousness.)
However, I'm OK with storing the ILEs here as long as they're easily findable. As long as the games forum doesn't grow beyond a page, that shouldn't be a problem. In fact, they may be more findable that way than they would with child boards.
