I'm psyched about GT5 too! I've played Call of Duty in 3D mode, but I just rented that game because few games can keep my attention for very long. I wish they'd release a 3D patch for Borderlands... I've been hooked on that for a year lol.
But GT5 is going to be amazing. I've downloaded Super Stardust, Motor Storm, and Wipeout. Super Stardust I think is a great example of how cool 3D effects can show depth, like whenever the ship explodes it's amazing how it make it feel like it's exploding forever into space. And when one quarter of the big UFOs explode and the 3D effect makes it look perfectly like it's just that one side.
Motorstorm is fantastic too. I noted this in another forum, but I like that people are designing these 3D games with smaller screens in mind, because some of the 3D effects of IMAX movies (like any of the "chase" scenes") don't have the same impact on smaller screens and the 3D doesn't look as immersive as on a giant screen. However the 3D effects used in games do amazing jobs or recreating depth. I haven't played all the way through, but in Motorstorm when you get dirtbikes, the 3D effect is so cool. And the taunts where he turns around looks like his hand is coming out of the screen lol.
In Wipeout, the 3D effect is good, but not as good as I was hoping. some of the parts of it do look awesome, like when you launch missles and they explode, or when a ship in front of you drops the mines. One other 3D effect that I've really started to love is in that game too (and used well in Bloody Valentine), that's like the HUD. The HUG looks like it's outside, framing the actual image. In My Bloody Valentine, when the camcorder was dropped and a naked Jaime King was running away lol, the information like battery, time, etc again looked like it framed the main image. Cool effects
I'm going to look through this whole long forum, but what are people's thoughts on PAIN? I think the 3D would look cool but I'm not sure how much that game would keep my attention. And Hustle Kings, 3D pool sounds cool but I can see it getting real boring real fast.
