10. Puzzle Quest: Galactrix

We're big fans of Puzzle Quest: Challenge of the Warlords on the IGN Xbox team, and not just because it has such a long name. Without question, Puzzle Quest is one of the deepest experiences you can have on Xbox Live Arcade, which is no small feat for a game whose main element is basically beefed-up Bejeweled. Not content to sit on their laurels, developer Infinite Interactive is stepping things up for the sequel. Now based more on Hexic than on Bejeweled, Galactrix takes the puzzle/RPG hybrid idea into the sci-fi realm. We still know very little about Galactrix, which is why it's on this list. How will the world map look? How do the puzzles play out? Who are the characters? We need answers, and we call upon the E3 gods to provide them.

9. Dead Space

We'll be honest. Until recently, we've been on the fence about Dead Space, EA's upcoming survival horror first-person shooter. But recently our interest has been seriously piqued, and we're getting more and more curious about this new IP. Dead Space is due to release this fall, alongside a flurry of other top-notch shooters (many of which join it on this list). What makes it different? Just how scary is it? Are the weapons, locations, characters and storylines compelling enough to make it stand out in a crowd? Proving that will be a tough task for EA, but we're hoping to be wowed.

8. Left4Dead

Survival horror games, or variations thereon, will be well represented at E3 this year, and Left4Dead looms tall among the them. Valve's co-op zombie-vs-human shooter has been on our radar for some time now, and we're ready to see in full-fledged horrifying action. Left4Dead's retro zombie movie aesthetic, intense action feel, sharp AI focus and overall creativity set it apart from the pack. At E3, we want the opportunity to play as both the humans and zombies to get a feel for both sides. Valve + zombies + guns = lost editor productivity.
