Ok... after the initial game overload and some more time to check things out, LBP remains the top show for me. The entire package is just so creative and strangely attractive. I think my family will get sucked into this not only for gaming.
The other trailers/walkthroughs are all very good but I can't rank them properly because they are all so unique in their own ways.
KillZone 2 is intriguing to me not because the developers could close in on the render target. I like the convincing "war theater" mood, and love the weather idea (I criticized Resistance for not capitalizing on weather as gameplay elements a few months ago). I also like how the NPC characters seem to draw and immerse me in the story/battle. But it's too early to see its full potential at this point.
Drake's Fortune is another great one. In my mind, I rate this on par with KZ because the character expression and movement exudes promises/potentials in a more organic and engaging experience. The graphics looks nice too (but I'm less anal in this area than many here
).
Heavenly Sword continues to amaze me with its fluidal combo/animation and *explosive emotions*. I absolutely love the last trailer link I posted in the HS thread.
The other great trailers (e.g., MGS4, CoD4) and game concepts (e.g., Echochrome) are all extremely high quality work. I will have to find time to revisit them when more info is available. I really like how nextgen is shaping up -- aside from the price point.
I think if I'm not fooling around in LBP, I will linger in Heavenly Sword, Lair and Drake's Fortune levels a lot. They are very pretty. I would like to take this opportunity to thank the developers for putting their hearts and souls into these games. I look forward to the purchases (and I'm sure you too ;-) ).
