Semantics gents, It "feels" like MoO2 without being a copy. There are both similarities to MoO2 as well as new and novel approaches. Add to that a bit of some other titles and you have ISG. It is potentially the best game since MoO2 to retain the style and flavor. Clone, spiritual successor... what does it matter in the end? What does matter is that it seems ready to scratch that itch we all have for a "modern" MoO2 "type" of game.
