German colonies in South Africa in WW2? What?
Though I agree with his points, I can't imagine big publishers would like to fund any game that doesn't have the "right" nation in it (i.e. it's gotta be good vs bad - American/Allied/Soviet campaign vs baddies).
It could work for an indie game, but still the playerbase could end up being a small niche, since you'd really need a lot of advertising to draw in a larger crowd. Escpecially if we're talking about Manchuria or Burma campaign.
I, for one, would love an Axis POV game, either from an enlisted or an officer's perspective. Both can include moral dilemmas and experience the gruesomeness of the war.
Oh, and this: As he said, the European theatre is overexposed, but only the 20% of it has been represented in games. We still haven't seen the siege of Leningrad, the Demyansk pocket, the battle of Smolensk, Dunkirk, anything from Operation Zitadel (AFAIK), invasion of Poland, Norway, and if the author is into the whole guerrila warfare, there's no better place for a campaign like that than Poland or Yugoslavia. The only problem there lies with the choice of perspective, since many resistance (and collaborator) groups fought each other as well as the Germans/Italians.
