i love how most of the music so far is remixed from super metroid, which had awesome freakin music. and yeah the intro had the signature 4 low pitched notes from the original metroid
yes lock on/free aim is cool. advanced is good because you can turn quicker, and you get used to the sensitivity. it seems that twitch motions are more accurate with a mouse though imo.
it would seem more natural to have jump be on the nunchuk with the morph ball on the wiimote, but then the targeting would be difficult.
it influences so much because it becomes a part of the gameplay. thats the genius of the wii.
