After a delay, KOF '98 UM Final Edition is available.
Played some matches online. Connection quality is all over the place. Some matches I played were absolutely horrible, XBLA '98 UM bad. Others were actually pretty decent, and a few were really good. So I don't feel like I got ripped off, but I also went in with very low expectations. When things were bad, the game just became about who had the best character for lag-spamming. Heidern is amazing when there's lag, BTW.
Playing this was just so damn awesome, though. I haven't touched '98 UM in at least four years and forgot what a fantastic fighter this is, especially with those changed-up EX characters. <3
Might just be a coincidence, but the first few matches I played were complete shit, connection-wise. Then Steam went down for maintenance. When I tried again, everything was better.
