Since it's a completely different game, do you think it'd be worth it to make a separate page for it? I'm really interested in it as I'm sure many others are.

Regarding Half-Life 2: Survivor
It's not worth making an extra page for it. The entire game is just a rehashed version of Half-Life 2 for Japanese arcades with nothing extra going for it (besides some small additions here and there with a horrible UI). Whatever things that are worth mentioning are already talked about in that Facepunch thread or in the Wikipedia entry. It's best to consider it a variant of Half-Life 2.
That being said, if you want to make it a separate page, go ahead. I just think nothing new would be added to it at the moment.
