JJ2... best game ever? More like one of the worst. Seriously here is a 2D game made in the 3D era. Not nessesarily a bad thing, I like 2D platformers, but JJ2 brings nothing revolutionary to the genre, in fact it takes quite a few steps back from JJ1. Let's take a look at what made JJ1 fun, for me at least, and compare it to JJ2:
First of all we have incredibly fast gun blazing action, you run and shoot like crazy; in JJ2 Jazz/Spaz/Lori moves considerably slower, the abilty to walk instead of run might seem like an advancement, but I think it kinda sucks, in JJ1 you were forced to charge full speed ahead through everything, in edition to that the new smarter enemies like the bees and ghosts slow you down because you have to STOP and jump around to shoot them, this isn't challenging, its just a pain in the a**. The ammount of ammo you can hold is also greatly reduced which makes the game less of a shooting frenzey. OTher thing I liked about JJ1 was its outlandish and often down right wierd landscapes and music. JJ2's landscapes are pretty, no doubt about it, but they are so dull compared to JJ1's. Same goes for music, tis very nice, but much more conventional. Finally theres the plot, yes, the plot. Remember the cheesey little stills at the end of each episode in JJ1? Theres nothing in JJ2 except the very conclusive ending movie. Deven gets smashed by a rock and Jazz gets married. The developers knew that they had lost their touch and didnt plan on making a sequal. Yes there was JJ3 later, but it didn't ever ammount to much did it?

I'm almost inclined to vote for JJ1 in this but you'd have to hold me at gunpoint or give me lots of money to get me to vote for JJ2.
