Here's a game I found on That video game site created by Tony & Matt St Leger.
My opinion of this game is split. While I think that it's a good premise for a game, particularly since I found it while searching specifically for a game that would allow me to fight the KKK, I still can't help but feel that it simultaneously uses some tired racist tropes. Then again, maybe not, as spinning-razor-guns aren't stereotypically employed by African Americans and are more reminiscent of Bond movies.
I can't help but wonder if The Fresh Prince vs. the KKK is maintaining racist tropes while (literally figuratively) fighting racism...?

Despite significant controversy after this games release way back when, this game is still available for play at some of the major flash gaming sites.

Yes, it says "There is one simple objective to this game, Keep them out... At any cost" with a list of the "enemies": Mexican Nationalist, Drug Smuggler, and Breeder.
Now, I know I said it before about the Ethnic Cleansing game, but there truly are so many games which leave me fairly speechless. Not speechless enough not to write this, obviously. Verbally, however, I find myself only able to utter a few guttural sounds of disbelief, aside from a couple of "What the fuck"s. That racist bigots use video games as a mode of social commentary and a device to spread their hate isn't terribly surprising. It's a powerful medium which gives pleasure to the player - the ideal platform.
