Thanks for the lengthy reply H.G.; the explanation of shogi-like variants was a good reminder to me about those CVs.
One doubt I have though is that Ultima games normally at least include chess kings, and checkmating one is always at least one victory condition one can have in a given game, at least if we exclude something like Bombalot, which has no K, but is otherwise Ultima-like (so I'm not at all sure why I should reject them as CVs). This comes pretty close to what Fergus wrote about when he defined what a CV is (or is not), in the link I gave in my previous post in this thread. I can also imagine that some Ultima piece might be created (besides a chess king) that has (or has as an option) capture by displacement. Arimaa and checkers, on the other hand, are clearly not CVs, and indeed Fergus' article in the link I gave does single out checkers as not being a CV.
