Well, one of my issues with UFC was the lag (like most other players said), and I probably revived 80-90 times, but what we gamers love about SK is the evolving storyline. Adding harder versions of existing bosses is fun for people who have become legends, but the majority of us would like more variety. Of course, add harder tiers and bosses to keep those legends happy, but please don't forget about the bulk of your fans....we like new content as well.
