KOFXI is excellent!
I bought KOFXI when it came out the first time, and I have to say, having the game for over a year now, I'm still playing it. The game system is excellent with quick shifts, combos, and the large cast amount of characters. This is a MUST BUY fighter for those who are into hardcore tourneys (or try to go to them) and for the casual fighting game players out there. Or if you just like the KOF series, this is again, a MUST BUY!

King of Fighters XI
I can't believe I waited a whole year to get this game. KoF XI is one of the best fighting games to come out in a long time. Highly recommended for the 2-d fighting fan!

Pretty Good
This game was my first import. I play allot of fighting games and was told that this was the best King of Fighters ever. Right of the bat you will notice that this series is finnaly new user friendly as all the special moves are easy to pull off. The graphics are no were near the quality of Guilty Gear and the animation although no were near Street Fighter 3 3rd Strike are still pretty good. Overall this is a fast moving well balanced and fun game and any King of Fighter fan should not miss it. On a final note I find it curious that bolth the character animation and graphics of these characters is much better in Capcom vs SNK2. I hope that in the future SNK brings the graphics up to modern standards as it would undoubtably be in a leauge all its own at that point.

This game owns all KOFs
Not only is this game fun but it is actually a challenge,esppecially on the hardest difficulty,Kof fans must have this game,MUST,It took about a week but it was definitly worth it...

Excellent
I know everyones already said it, but this is an awesome addition to the Kof series.
Character roster is tight, engine is rock solid and Oswald is a beast. Lots of people are still playing 2002 in my area, and should be playing this. So should you.
If you know your Kof, you should try XI(and Snk FINALLY cleaned up the visuals- xi looks great on arcade and PS2).
