Casualties? Hamas wanted to kill as many citizens of Israel as possible, no matter of what nationality they were. Even tourists were killed. Casualties are about bad luck, but Hamas victims were murdered because of evil intention. They cannot be compared to Palestinian casualties in any way.
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.
