I'm in NJ, USA and played a guy from Belgium, Europe the other night. We were fine until we desynched. This is on Live, btw. There's no reason the original game (along with the patches and compatibility packs) shouldn't connect with the KE. I bought the KE for the PS3 in early Aug. and played perfectly with a friend of mine who was using the original for two weeks before it began to desynch. Since then it's gotten so bad that I gave up on the PSN and went back to Live, only to find it is also desynching. There are more problems with MK now then ever before, and I've just about had it. I don't think they care enough to make a functional game so much as they care about hyping their next project to make the sales they need to stay in business. Meanwhile the ones who buy it and try to enjoy it are completely screwed.
