It depends really.

As far as 2D fighting game engines go, it's a pioneer without a doubt with many possibilities, in fact i love how you can actually "replicate" many real games using it and all that jazz.

So yeah, it could be a 10/10, but... the lack of updates is pretty much a downside in my opinion, also a lot of configurations are not intuitive at all, like graphic ones.

8,5/10 for me.
