Guilty Gear Xrd is on Steam and on sale (20%, HKD 142.40, USD 18.37 according to Google), it will end in less than 30 hours.
Some reviews mentioned technical problems, but so far I encountered none of them out of two days of play (2+ hr sessions). The key bindings a little bit inconvenient (keys to use navigate menus are separate from those you use to play and cannot be remapped), but the devs responded and are looking into improving it.
So far it's a blast. Very pretty, solid game play like previous Guilty Gear games. A very detailed tutorial mode, arcade, M.O.M., vs (off- and online, haven't tried online yet), challenges and missions.
Gallery to collect stuff with virtual money, unlocking art and voice packs, and more characters in the future.
And a story mode where you just watch - multi-episode fully voice-acted animations, broken into chapters (between which you can save/quit). It's *REALLY* long. I've spent over 2 hours on this and it has no sign of ending yet.
Music rocks like usual Arc Sys games, and the graphics are supreb - the instant kills and overdrives especially. I'm very impressed with Sol's Dragon Install - I scream like a madman when I use it, and I am scared when the AI boss use it.
