Okami is “Zelda-like” in its kind of medieval fantasy, action-adventure presentation, and in the way towns and NPCs feel, and perhaps in some of its bosses, but really it’s not all that much like a Zelda game. Okami is an quite standard all-ages real-time-battles RPG, whereas Zelda usually have no RPG mechanics - usually Zelda enemies are defeated in just one or two hits, with little or no stats, points or inventory. Zelda games usually have a lot of focus on puzzles and dungeons, or dungeon-like outdoor areas, whereas Okami has no puzzles. On the other hand Okami is obviously very steeped in (often silly or humorous) Japanese folklore, whereas Zelda is very much less wacky and often a little more emotional and dramatic, and has its own bespoke theming.
I liked Okami but I felt it was paced really quite slowly, and the battles/enemies were a little too RPG-like for my taste, as in taking quite a lot of real time for even weak enemies. I felt it lacked the mechanical polish that Zelda usually does: I felt generally the movement was a little slow and difficult (except in very open areas) and most disappointing of all was the frankly poor recognition of what brush move I’m drawing.
