I got the urge to start making stepcharts again, so I grabbed StepMania 5 and, for the first time in a long time, I've actually been impressed by a mainline StepMania version. Making SM-SSC the mainline branch was the best idea the SM team ever had. I've never played with SM-SSC (I've been away from SM for quite some time now) but now I wish I would have earlier. It would have probably been enough to make me interested in charting again.
I think I'm going to have some fun with the new scroll options. I've never been a fan of the concept of lifts (or rolls, to be honest), but I like how we can now, at long last, truly make PIU-style psyche-out charts (without resorting to bizarre glitches that should have never worked and other things -- like fakes -- that would have been impossible to properly do in 3.9/OITG), and make different scroll types for different difficulties.
