Impressed with Hyrule Warriors so far. I haven't kept up with Dynasty Warriors after playing Dynasty Warriors 6 so the engine seems a bit new to me. Not sure I like the 2500-3000 KO's each level. The peons have become too easy and passive, rendering them obsolete. Really the only guys who are any trouble at the bosses.
The bosses are unique, since with the DW engine we're not used to fighting gigantic enemies. This can be a problem when they jump inside the main base, and if you lose the base you lose the level.
