Guilty Gear Xrd -SIGN- was just released on PC via Steam (in addition to the current PS3 and PS4 versions)! This is my favorite fighting video game series. The characters, music, story, graphics, and competitively, the depth of strategy, combos, degree of freedom and room for individual style are all amazing. Let's play!
It's worth noting that for its first week on Steam (from now until December 16th), the game is 20% off (bringing it to $23.99), and the DLC is free.
Here's a list of resources for this game that I've compiled for everyone:
(There are also video threads in the subforums on Dustloop!)
BROKENTIER'S SIMPLE CHARACTER GUIDE. (This explains character traits and general strategy, with videos and examples of high level players. This is for Guilty Gear XX Accent Core, not Xrd, but can still apply if you are trying to understand the returning members of the cast and choose a character to play.): http://blog.brokentier.com/192/guilty-gear-simple-characte-guide/
Beyond all that, there are countless character-specific guides on YouTube. I recommend looking those up after you've chosen a character as your main.
Please let me know if you need stick mods or repairs!
