Well a lot of the easier charts used to have very fun footwork, though would usually be pretty easy to play they were fun and the songs were good, like Spin The Disc. Easy easy chart, but fun as hell to play. A lot of the new charts just seem way to lacking though, Koonami seems to hold back too much with non boss songs and go all out on boss songs.
That has to be the only reason why I liked ITG charts was that they all had oni charts (though yeah a lot were crap it still had that one tougher chart which if stepped right could be fun.) Gold Rush seems way way way to easy and under stepped, at least charts like Fire Fire look really fun, and not like zomg tough fun just looks fun to no bar fun. They seem to be heading in the right direction but I'm still kinda disappointed to see Gold Rush get such a weak chart.
(hope some of it makes sense, idk I haven't played ddr in ages)
