Really, the simple thing to say would be that it's not as good as the first one in my book after putting countless hours into it.
Do people even use Techs? I never use Techs since they just screw up my turns while being useless about 98% of the time. I only use Scouts so I can make them Snipers since the Scout guns are nowhere as good or as useful. The song classes are a joke, the commands suck in general. The entire game you only use Lancers about 5% of the time and the rest is just Shocktrooper tree and Tank raping everything with 1 Engi. The first one gave you classes and advancements that made nothing useless, every class was useful in the original, was it even made by the same team?
The objects were not repeats of themselves every month (chapters in the first.) The grand story is much weaker, and though the multi map is a good idea, it's not as grand as most single maps in the original.
It's also not anywhere near as hard, I certainly don't dislike it, it's just not as good as the first one imo.
Also, what's up with only 1 tank? I had 2 to fuck around with in the original god damn it! 5 member limit in one area and 6 total? sigh... I want it to come back to PS3, or maybe 3DS =P.
Thoughts?
