What other games use it besides Eye of Judgment (Which I personally hated-- and I even love CCG's)?

I thought EoJ was a good idea but i'd prefer Yu-Gi-Oh .

Um the eye camera isn't worth the purchase right now , not properly supported by Sony.

the PS Eye also allows video chat with other PS3 users, and some games use the PS Eye like Burnout Paradise.

I agree, Sony should market it more. As a consumer I was not really sure what it was used for.
The chatting feature might also be useful, but it's limited to your friends with ps3 eye, and they are sill too few.

Still, thanks everyone for your opioins. I will buy one and have it a try.

 You can video chat with anyone with a PS3 and network connection.... Just that if they don't have one, you won't see video of them, but they can see you.

 I have a couple of friends in Iraq right now that use the PS3 and eyetoy to communicate with their families/friends back home. 

Yes it has a microphone in it for online gaming I think.

if you have a friend with some other form of webcam, they can use that as well.

Burnout, Trials of Topoq, Operation Creature Feature, Mesmerize, Tori-Emaki, Aquatopia, and a few others. The latter 3 are mostly tech demos. All except Burnout are on PSN. I say a few others because I thought there were a few games that use it, or I could be thinking of future games. Anyway, I still think Eye Create, which is free from the PS Store, is the best feature so far along with video chat. And like I said, video chat also works with other USB webcams.

i have one along with the games:

1. EyeCreate- FREE-----Rating 8/10-----Fun to make movies with your friends but could have more editing feature IMO but its free so you really cant complain
2. Mesmerize $1.99 ----Rating 4/10 ----Pretty pointless application
3. Aquatopia $1.99 ----Rating 1/10----Waist of Money...cant every see myself wasting time loading this up to feed fake fish. Also i am really into Marine Biology and it angrys me to see that they have saltwater and freshwater fish together... i mean really who payed these idiots.....
4. Trials of Topoq $4.99----Rating 8/10---fun but does get kinda boring. Would be cool if they had a online mode that you could race other people around the world. But if your with your friends its really fun and uses the eye perfectly
5. Turi Emaki $1.99----Rating 7.5/10---suprisingly this was very very fun...i couldnt believe i spent like 2 hours flying around a painting

All and all its pretty fun...but dont count on the mic for online mode becuase my friends tell me i sound terrible on the other side when i am playing with them online...so i switch back to a real mic....

HTH
