[Question] Unique game mechanics -- The best and the worst

The worst: Easily/no-contest/undoubtably the Resident Evil 3D controls...When you're NOT in a 1st/3rd person perspective. So you watch you character turn in place and press up to move. NO...Just, no...It's so fucking wrong, I don't how survival horror fans tolerate that shit. I played both RE 1 and Dino Crisis (and various kiosk demos) with it and it's easily the worst I've felt playing a game. It's unique because it seems limited to horror games...So I avoid those, I avoid those awful controls. Problem solved.

Best: Valkyrie Profile's combat system. Beautiful pyro and endless customization at the push of 4 buttons. This is something I wish more games would rip off because it's so damn fun.

Roman Cancels from Guilty Gear also get a mention...Once you get used to pressing the three buttons in the midst of a combo or attack string, it opens up a world of new potential. This is what makes GG far deeper than an average Capcom fighter, IMO. Also of note would be Burst, which can be really effective offensively and defensively. On a side note, instant kills would be a candidate for worst mechanics if they weren't so obviously for showing-off/messing around/killing newbs off. The ones in GG1 though...Awful shit, no matter how you slice it.

And I feel like I'm cheating with a novelty peripheral, but the Guitar Hero controller is really intuitive the more time you practice with it. A few weeks ago, I felt awkward moving to the orange fret (people going from medium to hard know what I mean) and I was really stiff moving around on it, but now I feel really comfortable with it and I don't even pay attention to what finger is hitting what fret or panick when I have to switch to a double-strum...It's really fun to play now that I've gotten so used to it.

Jam it back in, in the dark.
