So my friend bought this and since I'm a fan of 3 and played it a lot we gave it a try. And my verdict is: it's pretty bad. You feel slow and the input lag is pretty bad or it feels sluggish rather and attacks feel weak and there's no hit stop like 3. Combat also feels slower in general. And one thing that really bugs me is when you start it up for the first time you can't adjust your settings till after your first fight (can't change settings in missions at all). Meaning I was stuck with the camera y axis set on normal and was having a hard time fighting the camera. Oh and the part swapping? Cumbersome and annoying. You can only pick up and hold on to like 7 or six at a time. So running around picking up, switching, discarding and equipping them detracts from the fights. It's not fun.
Also it takes longer to load compared to 3 too since I booted it up after to compare. 3 also just looks better in my opinion, plays better, combat is better and loads faster.
It's a shame we finally got a Gundam Breaker game released outside Japan but it's a game that's hot garbage.
Just get Gundam Breaker 3 Break Edition, it's a better game.
My friend agreed and was disappointed so we went to return it and he ordered 3 from playasia.
