I think I have found out my ultimate decision for this game.
SirJackRex, If you don't like it, STFU.
I think the graphics of this game have not improved enough to stand out from MP2, and the blurred flat textures on things could be so much better now. It looks like exactly the same game in the series, a few new gizmos and gadgets to sparkle it up, but flat out it is the same game. On the other hand, this game series is still great. It is a great flowing game with large scale enviroments and alot of things to do. The puzzles don't seem to stand out, but actually go and flow how things would actually work for the game. The controls were great for the Gamecube, and brought a new perspective to the Metroid Series. This next (final?) installment is something I am looking forward to, if I get a Wii. It is a good formula for the game, and the Wiimote will only make it better.
Score: 85/100 Although graphically and gameplay, it is the same game, despite new monsters and areas, plus a few features, but it is still a great game series, with excellent controls and a great enviromental feel that puts you in Samus's hot. HOT body. :p
Now can't everyone agree with that?
