On some level, yes, Israel's Declaration of Independence could potentially be a valid topic for a pedagogical game, but even if this game underwent substantial revision, I cannot think of a single classroom I have been in where the premise, text, and appropriateness of this game would not be immediately and wholeheartedly challenged by the entirety of the student participants
I find it interesting that you say you've run participatory classroom games on topics such as genocide and slavery—I have a hard time imagining how that could be possible with regards to ethics and safety. If deep care was taken in their design, I would be very interested in seeing how those games work. I can only hope they were not written with such a deeply uncritical design, and with such a hegemonic voice and POV as this one
My biggest problem is that your game text, the authorial voice, your own voice, 1) mentions only violence against Zionists and Jewish people (the sole semi-exception, you say: "Atrocities are committed on both sides"), 2) does not clarify any difference between Zionists and normal Jewish people, 3) hagiographizes 'Great Men', 4) does not reflect at any point on what it might mean for a classroom of students to play all men, all Zionists, all ethnosupremacists, all nationalists, to themselves 'play' as architects of a regime of genocide and apartheid, without even a mention of safety tools, 5) reproduces the lionizing narratives of a genocidal state as that state at present is undertaking a wholesale genocide in full view, and so of course it makes sense that your game 6) erases Palestinians. You literally refuse to refer to Palestinians at any point in any of your work. Those who oppose Zionism and their genocidaires are simply "Arabs", implicitly non-native non-nationals, and you use the word Palestinian only in a single instance, as an adjective, to clarify a certain kind of Arab. The point here is not that language is important. If you simply revised the text to include the word Palestinian, your way of thinking (whether your own or—if I'm feeling very very charitable—imported from a wider hegemonic discourse that you've thoughtlessly reproduced) still informs the entirety of the structure of the text. You say that Palestinians can go have their own things, make their own things, too. You say that this game is about Zionists, and to each their own place and thing. I think this stinks of apartheid, as does your game, on a meta level and a functional level. It is simply not a critical work, it is useless, it is at worst dangerous. At best it's not worth even the amount of words I have already spent on it
There is a genocide going on in Palestine, against Palestinians, right now, just as there was in 1948. Your work here is completely inappropriate and unsalvageable. The kindest thing I can say to you is that I hate it
