It might not be the best thing for AAA multi gigabyte games like Crysis 3 (yet), but it makes sense for alot of smaller scale projects, especially online games

It might not be the best thing for AAA multi gigabyte games like Crysis 3 (yet), but it makes sense for alot of smaller scale projects, especially online games (typically free to play) where the barrier to entry is low. Longterm in also makes sense to think of games loading on demand while you play vs downloading everything to disk and install it somewhere. It also solves alot of the piracy problems of the industry. Today there are Game Engines like Unity3D that already offer Native Client deployment and have their own browser plugin for IE or anything unsupported. Add to that a HTML5 deployment option through Emscripten & ASM.js and the games will basically run anywhere, just in edge cases requiring a plugin.
