#1 Why do you think MQ is good?
The strategy is much more advanced in comparison to AQ or DF as you cannot change your weaponry during the battle, meaning if you have a glaring weakness to either a status effect (like stun), then you are basically screwed. AQ revolves around long term planning and elemental set ups, as well as reducing damage. DF revolves around having the best combo in the class being used. MQ revolves around the best set of equipment to beat the snot out of anyone, which can either be through all sorts of status effects or high damage.
#2 Why do you think it's bad?
The storyline seems a little off, as we randomly go to planets, and they happen to be in trouble. And the shadowscythe have disappeared from causing anything. And I miss the J6 side storyline.
I dislike the small cap raises, making it far to easy for those who are close to it or already there. Then cap level mechas are released and for some of us, that cap mech is more important than getting anything else.
I also hate the nova gem prevalence in this game. The best of anything is nova gem, which is understandable, but combined with the small cap raises, nova gems feel incredibly common. Wouldn't it be better to have a nova gem shop, headed by Sys Cero or even Tek, which wasn't just the best mech of the week, but many different good mechs to choose from for different levels.
And I don't like the expensive nature of mechs in the lower levels. I understand mechs reaching a quarter million by level 25, as the credit earned each level is decent enough to get them, but at lower levels, the ratio is not nearly not good, and thus, the mechs being 100,000 by level ten is just too much. Maybe half that, but not more, that number should be reached by 15 or higher. Currently there's no real point to not leveling up, as only the higher level mechs are powerful, though the revivals are fixing that as we go along.
I also dislike the random encounter engine, as generally when you're fighting with a default mech, you can last up to two times against the AI, but after that, you're dead, the encounter rate is such that you can't get very far sometimes, and that's just annoying, for me at least.
#3 What makes you play MQ over other games?
To get to the cap since it's relatively easy to get to, or to get the newest mecha.
#4 What doesn't make you play MQ over the other games?
Nothing to do other than get more mechs and advance the storyline.
