You can't go wrong.
Pretty much the best 2D fighting game ever made.

Guilty Gear never miss!
I've played almost all Guilty Gear games, this is a great game and is highly suggested to anyone who likes a bit the fighting games!

Upgrade from Slash that does a great job!
I have been playing the GG series since 2001, and I have to say, this is by far, the best one of the series. The updates are excellent, with new moves, combos, balance tweaks, and even hidden supers for some of the characters! The graphics are fixed up a bit, some stages are new or have a different setting. The voices have been changed, and yes, the announcers voice may be annoying at first, but once you get into the fighting, you ignore it. It is a MUST BUY if you like the series, or you play it in tourneys, or even with your friends!

Overhaul
GGXX AC has some major balance tweaks and audio/visual changes that leave me with mixed feelings. First of all I don't see why they kept I-NO as the final boss. She is way to strong compared to the other fights in arcade mode. But instead they ruin characters like SOL and JAM saying it is necessary to establish the new fighters. By the way: There are none. This is ARC System's way of saying thanks.

No glitches so far (crosses fingers)!
Great sequel to end all sequels. A lot of rebalanced characters at the expense of others. Cool new tracks, as expected from ARCSY, but dammit the new voices suck, reminds me of the time Capcom used that lame-o announcer for SSFIIX. Maybe they got the same guy to do ths game?

As usual, all this is just practice, see you on the tournament circuit! Heaven or Hell, LET"S ROCK!
