A significant improvement on The Daleks in Colour. The story is mostly intelligible, albeit with the occasional bit left hanging (e.g., how did Lt. Carstairs come into it?). The colourization itself is also much improved; whereas The Daleks had the look of '60s colour TV like Bewitched or I Dream of Jeannie, with the colours rather pastel, The War Games is still somewhat muted but looks more realistic, similar to the 3rd Doctor era.

On the downside, the continued attempts to modernize the look of the story with CGI inserts and fast edits, particularly cutting away from dialogue to make a voiceover, end up detracting from the experience by making it obvious that it's a re-edit. The flashbacks to The Highlanders and The Wheel in Space are particularly gratuitous. (But at least they didn't do any dizzingly fast, flashy edits like in The Daleks.)

As for the story itself, I enjoyed it and look forward to watching the original.

Nitpick: Using exclusively Nu Doctors as the Doctor's possible regenerations undermined the attempt to connect Classic and Nu. Should have been the War Doctor (too old), Ten (too thin), Five (too young), and Four (won't do at all).

EDIT: I've now watched the original, and the unexplained things I assumed were cut in the colourization... aren't there either. In fact, I preferred the colour version. So I'm bumping my rating up a half-star.
