Just from watching here are some things I appreciate about this game:
-The linear levels. I loved beating shit up in DMC4 but I always, always get lost in the friggin' castle. Yes, I play nonlinear stuff like horror games all the time and probably have no excuse. But I'm fine with not getting lost sometimes, especially when I just want to get to the next wave of assholes.
-Move names showing up under the style meter is cool.
-I also enjoy the tips mid level about the different effects of attacks (like parrying projectiles with Prop Shredder). These would have been handy in other games because there's SO much you can do that you'd otherwise miss without reading an FAQ.
-I'm not crazy about collectibles counting towards a level's final score but at least they stay "collected" once you get them. Having to hunt down every red orb was a huge pain in the ass in other games. (DMC4

)
-Some of the music I'm not crazy about either but other tunes fit in very well with the style of music that's been used since DMC3.
-Though there is a bit of context-sensitive stuff, no QTEs in sight. JOY!!!
-Along those lines, no wall shimmying or super-slow platforming in that regard. Not that I play DMC for platforming anyway.
-All your weapons are available at once. (DMC4 did this too, but you had 3 at once where this game has 5.)
