Capcom had absolutely no trouble fitting a full-length game onto the DS. In fact -- and this sounds like a weird thing to complain about -- it feels overlong at its 20-plus-hour runtime. It starts slow, with a bunch of fetch quests that reduce divine intervention to a shopping list, and doesn't end where it seems like it should ... or even at the next natural stopping point. Though Okamiden hits a pretty satisfying stride in the middle, it is a bit of a marathon.
... OK, yes, an adorable marathon.
