See, FOARP, most of the time i agree with you - but on this, i think, your position is testimony just of how much you have been involved with HoI. Because, for a newcomer, someone with the intention to have a relaxed evening, possibly after hard-grinding work, the reactions to the first sight of the map and after that the first scroll in, that i have seen, match those descibed by Nick3210 pretty well. Where you clap and rub your hands with a big fun-anticipating smile on your face, these people shudder and simply feel overwhelmed and even intimidated. It gives an impression on how long it will take to even start playing this perceived monster of a game, let alone finish one match. There are people, who do not want to make it an important part of their lives - and we´ll have to face that. In fact, by offering ´lite´-DLCs, we could all profit from it. PI gets additional sales, we get your grognard-version first, and people who before would not have played the game might enjoy the fun even if on not quite the scale the ´original fanbase´ prefers.
Personally, i would probably play the big version in SP, and the small version in MP, preferably. Assuming i could talk at least one of my real-life friends into it (because of the reduced scale), i´d probably pay another 20 or so, for it. If the maingame is on sale by then, for say another 20, that´s 60 (2xDLC, 1xgame at discount) extra for PI (well, yeah, i know, not quite...). Just saying...
