This game looked like a scam before release. The developers copied art style and their trailer scenes from other games, and never shown gameplay videos. In the trailers it looked like AAA, but was developed by a studio without required experience. There were doubts the game existed at all. Well, it existed, but was far from what trailers shown.

Somehow it turned into blacks vs whites, which is not ok for me.

It depends on country. There were countries where indentured servitude was for entire life, except for cases when a landlord freed a serf or a serf bought own freedom. Landlords could buy, sell and judge serfs. Example: Russian Empire, where serfs had no rights.

Thats an overgeneralization. Some white peoples were enslaved while not all black peoples were slaves. The question is more complex than presented.

I hope they will return the original Angry Birds series to the stores.
