Games to make movies (Halo?)

AVAST! :pirate3:

So with the customization and power games now bring to the table, are they being used to make home-made CG movies? If I recall, there were some Halo movies like this… am I right in thinking that? I haven’t seen any; I think I just might have heard about it somewhere.

Anyway, it seems like an exciting prospect for games to present themselves as both interactive entertainment as well as non. Not only would you be able to play custom levels created by other people, but also watch movies created by them. Is there maybe some unknown underground movement doing this or is it something that kind of goes un-noticed… or do gamers even really care to make movies like this? Anyone know anymore about stuff like this?
