In the mid 90's, games produced on "CD ROM" format became available to the mass market for a relatively low cost. With a vastly expanded capacity for storage to work with, developers jumped at the chance to integrate "Full Motion Video" into their projects at a record pace.
When human beings suddenly can do something, they will do it, regardless if they should. That's why Christopher Walken, Dennis Hopper, and Cory Haim all threw in with some of the strangest, technically unsound narratives in the history of storytelling (in gaming or otherwise). It was a "look before you leap" time in development, one that yielded the kinds of games you just don't see much of anymore.
Tokyo Crash Mobs marks the return of the kind of surrealistic FMV gaming that I once thought was gone for good. The developers at Mitchell Corp. were clearly excited to try their hand at crafting some live action 3D cut scenes, though it's not entirely clear that they had any sort of "plans" or "direction" before they started production. What they did have is a green screen, a few models, some oversized business casual suits, and a ninja costume. The end results are nothing short of magical.
Oh, and they also made a pretty good puzzle game too.
