the reason there are no Canadians in games is that there were no new movies portraying Canadians in WWII. You see for some reason the gaming companies have it in their heads that all gamers are pre-pubescent console-kiddies who have not seen any war movie earlier than Saving Private Ryan. They seem to ignore the mature audience who have also seen classics like The Devil's Brigade and The Longest Day and actually know something about the war outside of what they learned in late-90s Hollywood.

This is the same reason that there are no Pacific Theater titles, the only movies as of late were Pearl Har-bore (more of a soap-opera during WWII rather than a true war movie) and Windtalkers, which I hear isn't much of a movie either.
And remember, we're all much to young and stupid to remember the older movies about the Pacific War, so to us gamers it doesn't exist rolleyes:
