Hello, I'm thinking of buying the SCII Blitzkrieg and WaW Bundle but I have a couple of questions: 1) Are Blitzkrieg scenarios upgraded to the WaW rules/units/etc...specifically, if I play the Global War scen from Blitzkrieg, will it be a Blitzkrieg game or a WaW game? Kind of confusing I know, but I I'm looking primarily for an ETO game and then a global game and that's why I'm not yet getting the Global Game; and 2) How is this game better/different from MH Commander: Europe at War? The two games are extremely similar but I'm tending towards SC II. Thanks. Chuck
