I purchased the first gamepack of Siren last night and played the first episode. It was pretty scary. I played it with the dualshock and the vibrations really added to the experience. I was going to play episode 2 last night but the preview of the little girl freaked me out. The graphics were pretty good, my only gripe was with the police car. It seemed a little last gen to me.
Also, I was able to play Pixel Junk Eden. I was very skeptical of this game. It has received a lot of positive press but the gameplay videos didn't seem like it would be any fun. I was wrong. The demo hooked me and this is a day one purchase. It is such a unique game graphically and musically. I hope more games support the in-game video capture to the HDD or upload to YouTube. This is a feature I will use a lot. I really like the direction the PSN. Sony needs to buy Q Games.
On a side note, the download speeds were great last night. I thought it may be an issue since this was a large release, but I didn't have any problems.
Thanks for the input, Jeff.
