After seeing the quicklook, I'm definitely sold on this. I only played the first Metroid Prime very briefly and didn't really give it a chance. I can't wait till this comes out so I can give this series another go. Anyone else in a similar situation in terms of not playing or barely playing any of these games?

I played the first and some of the 2nd I already pre ordered my copy u

I'm definately picking it up. I was holding out on buying Metroid Prime Corruption when I got my Wii because I didn't know the story or anything, but now I can get all 3 for the same it would've cost me just to get Corruption.  Win Win.

I had the first game but never actually finished it because my GameCube randomly stopped working.  I never played the second game, but I own the third although I'm yet to actually start it.  At such a good price I'm definetely getting this just for a chance to play the first two games again. 

50 bones for 3 games is pretty amazing. If dissidia wasn't coming out the day after I would have pre-ordered this already.. but alas I'll have to pick it up next month.

 
Definitely. Its more or less my most anticipated game despite its age. The textures have been redone, right? With Batman, this and Shadow Complex I've got a sweet couple of weeks playing games and drinking beer in the new flat before term starts.
