*I never played MK9
As a DC Comics fan I enjoy a number of aspects of the game.
The roster is great and has a wide range of characters from the DC universe. As a Batman fan I'm even more excited due to number of Bat heroes and villians. Each character plays as he or she is portrayed in the comic book. IGAU has a nice range of characters for players who enjoy zoning, rush down, or anything in between.
I would have preferred a wider range of stages. I like the way the environments are altered as a fight progresses and also the transitions. I could have done with 2 Arkham Asylum and Wayne Manor stages.
I don't have a problem with the fighting engine. The 3 button attack scheme, special moves, clashes, traits and other mechanics are fine. The system is basic enough for new fighting game players not to get overwhelmed but complex enough for us to dive into it. The interactables add a unique element to each fight. They can feel cheap at times but I enjoy the mind games between players as each of us wonders "Is he (or she) going to go for interactable?!" I've noticed each player uses the tools of each fighter in different ways. I enjoy watching other players use my mains while thinking to myself "I'm going to add that to my reportoire." The practice mode is one of the better ones I've used in a fighting game. Fights can get fast and furious although I would like to have a way to dash cancel.
The online aspect of the game is better than I expected. Looking at everyone's statistics and character usage is fun. It gives you an opportunity to size up your opponent. I do like the concept of the skill rank numbers. It's not a perfect system but I like what NRS is trying to do with implementing it. I have rarely been in a match that was unplayable due to internet lag.
I don't mind how the game is balanced out. I've never been the player who gets hung up on tier lists, buffs, and nerfs and all that jazz. I simply use characters that fight my play style and try not to get caught up in any drama. I choose to play games that have a community, reward you for improving, offers replay value, and are fun. IGAU fits all of those parameters for me so I'll be playing regardless until I choose my next fighting game.
I'll add more points as they come to mind....
