According to the Gamespot review of Assassin's Creed, "PS3 owners are blessed with a slightly more solid frame rate, although the 360 version features a little more contrast in the lighting, so it's pretty much a wash." I'm leaning towards the PS3 version but can't decide which version I should go with. Does anyone have any suggestions? The only other issue I can think that might be a factor in favor of the 360 is the Live features and Achievment Points but I don't know if that should be a compelling enough reason.

Any opinions?

I've taken the liberty of fixing your English. I think you need to pay a little more attention in school.

There is a Transformers game coming out and it looks interesting.Maybe they will get the formula right this time.

Regarding GI Joe: There is already a whole genre of gaming that has the goal GI Joe was striving for. Although, I don't see why kids nowadays want to buy a game that's about this old army figure.Just like Actionman, I love that guy, but he didn't get games made about him.Darn you gaming industry!

You can only use it at specific places where there is a statue holding a glowing green orb.  Then you press R1 and L1 and the same time to activate the amulet.  If you go to the items menu and select the amulet it should tell you which buttons to press.  It's been a while since I played the game so I might be wrong about the buttons, just double check in the item menu.

Since you said you have an Xbox, a lot of the multiplatform games are typically better on the Xbox (graphics, not picking sides I love and have both PS2 and Xbox). In fact you've probably played some of the suggested games that are multiplatform.

The series that stands out to me that is missing from the other suggestions is the Ratchet and Clank series. All four games, Ratchet & Clank , R&C Going Commando , R&C Up Your Arsenal , and R&C Deadlocked , were highly regarded and have a great sense of humor as well as good graphics, tight controls, and great gameplay.

Additionally Katamari Damacy and We Love Katamari are good games.

Virtua Fighter 4: Evolution is a tremendously deep fighter with a long and proud history. They actually coded some of the fighting tactics of some of Japan's best human VF4 players into the game's AI. I'm not the biggest fighter fan in the world, but this is a deep game that needs to be in your library.
