Wow, I can't believe this game doesn't have more hype going for it. I am one crazy Metroid fan, and I found myself not really interested in this one. That scared me, because I have owned each version so far, and I was thinking it was going to end this time around. I figured college would override my necessity for this game, and I was content with that, as I really hadn't heard compelling reasons to own it.
I thought multiplayer would be neat. I thought the duality was cool, but not clincher. I thought it was just going to be more of the same. Why didn't somebody hit me? Now, I generally dislike IGN's attitude, but recently they have been building hype for Echoes, (because they can see that there really isn't any) and now I'm hooked. I refused to look through the 75 new reasons to own Echoes, but just thinking about that is crazy. I can't wait to destroy my friends is a four player mode. I can't wait to try out all the new suits. I can't wait for the new visors. I just can't wait.
Somebody said Prime was built ground up in 1.5 years. They have been working on Echoes for 2, but they already had the engine this time. If you think they have played all their cards, you will be in for a pleasant surprise. Thinking about the unknown (the biggest part to any Metroid entry) has me stoked. Why aren't you?
