So, I'm not entirely familiar with the Vs. series... I own Gundam vs. Zeta Gundam and thought it was a great idea with terrible controls.
Since you all are hyping Next up, I went and tried GvG... It was slightly better. Instead of feeling like a slug, I felt like a slug on meth. I like having the OPs/EDs playing during the stages.
But if I'm understanding correctly, people play these games like competitive fighters, correct? To each their own, but that seems a bit laughable to me.
Personally, I'm a big fan of GBU and even NET because they make me actually feel like I'm piloting a mobile suit.
Not trying to troll or anything, just my opinion.
