That must’ve taken you a while to think up.
Yeah, I didn’t think about that. My suggestion is more about adding that song into the game somehow; the children’s area was just a quick idea to go about doing that. You’re right though, it would probably be oddly placed down there. I remember seeing in the trailer that there was a cafeteria/fast food area that you passed by, and possibly putting it there. Again, I care less about the children’s area than I do about that song being hidden like an easter egg somewhere.
As far as it being too late to add such an area, it’s not like I’m suggesting a new skin for the crates in-game. I used to map for a mod, and adding a small room with a sound box coming from to a single map it isn’t very difficult. Granted, that was on a different engine, though. Anyway, it’s just a suggestion. Should we limit our suggestions only to Xen, then? If so, what maps are and aren’t finished so that we can better direct our suggestions?
