Ok, I bought Rock Revolution. Drums and all. With GHWT and RB2 dominating music/rhythm games lately, almost no one has looked at RR. I found it at a discount and had a gift card, so I went ahead and got it.
And... It's not bad, not nearly as horrible as I expected. I'd go so far as to say it's better than DDRU or DDRU2. It's like Konami finally woke up to modern day consoles and features. Granted, it's a bit ugly and horrible as far as menus go. And there's that awful loading time between, well, everything. But the game itself is fun. The song selection is decent to pretty good. And the challenges are pure Konami Bemani. Perfect play of a passage, blind play, and poison notes all make an appearance.
I had some fun this weekend getting through nearly half the achievements - many more than I have in RB, RB2, GHWT, and GHA. All on guitar, as I set the drums up but didn't play on them yet. Some of the achievements are decent, some of them are way too focused on the high end - Expert appears in many of the remaining ones that I, of course, didn't get. However, most of the rest don't care if you're Beginner or Easy or Medium or Hard, and that's a good thing.
This game is currently on clearance at Target for $10. That's hard to beat. Konami, despite missing the mark and rhythm surge, isn't quite out of it yet. They have lots of work to do to catch up, but they made a decent start to it. The easiest way to describe it is simply RB or GH with a DDR/IIDX/Bemani feel.
