I have never even heard of that until you posted hmmm not really my thing but worth checking out if your interested which looking by your avatar you are

its good there are new fighting IPs still coming out.
Oh and there is also another free PC fighting game out called [b/]M.U.G.E.N[/b] which is highly moddable and has a few thousand characters, stages etc its worth a look anyway but obviously its not the most balanced of fighters but it can be good fun.
Also since you seem to be interested in Skullgirls I will slightly expand my very small original descriptive blerb basically at the moment it looks and plays well very well the tutorial is also great but falls down in that the training mode isnt that brilliant (at the moment) and there are no character specific tutorials basically I found it a fantastic setup but feels like there should be more still it beats any other fighting game tutorial I have ever played. The character roster is tiny like the original sf2 but each one feels unique and play very differently Valentine is my personal fave as she has a great rushdown game.
Single player feels very limited the story mode is naff and arcade dosent feel very progressive due to the tag team nature of the game and small roster you fight the same characters a lot, still on the upside at least you get to see what each can do. Also the AI is brutal they dont cheat (except the last boss) but they will punish you for any mistake even on easiest TBH it should probably be toned down a little.
Oh and last boss is absolute crap but apply that to every title I have mentioned except SC5 who dont have last bosses just cheating AI in legendary souls mode.
I think though by the time the PC version is released a fair number of these issues will be fixed including the lack of in game character move lists also the first 2 DLC characters will have hopefully been released.
