I'm in desperate need for a really good and deep strategy game for my iPad. I set my eye on the slitherine games as they seem to be a generally good fit for my requirements (i.e.: strategy & deep). The price is not an issue, it's more that I don't want to waste time. The problem is that there are so many of highly rated ones. Which one should it be, Pike & Shot? Battle Academy? Panzer Corp? ... So, which ones of the slitherine games would you guys recommend to someone who hasn't played or seen any of these yet?
