Fluid movement is nice, although a little awkward in a grid-based world (the same issue is present in Minecraft). For me, the annoying thing about the rollerskates is the little animations for putting them on and taking them off; they somewhat ruin the fluidity of one's transit over short distances. Also, a complete control listing for them would've been nice to see in the manual; I never took the bother to learn any tricks, and only incidentally found out how to move faster than the default maximum speed (which makes people's comments about how the skates aren't as fast as the bike technically untrue). I prefer them over the bike, in any case, since they don't have to be pulled out like an item, but that leads me onto the worst thing about them: they ruined some players' preference for fluid control of pedestrian movement using the analogue pad. There should've been an option not to use the rollerskates once one got them.
