I see that as really different. Both movies are animated movies are for the same kind of audience, and same kind of "platform" (theatre, dvd, tv), and they are things that you watch.
Games are completely different.
If we list games, we could also list tv-ads, etc. It will never stop then.
I think that it is better to do that on a separate website.
By the way, adding games would require even more time from me (and IMCDb already take lots), and more space on the server (we reached 1 GB of pictures...)
