having now had a chance to fiddle about with the Vassal mod, I can see exactly what you and Vance mean. Its just a different approach, but, at the end of the day, its really nothing that different that some other tac level games. I do like the way all combat is resolved after all action/ reaction have been conducted, but again, the end result is no worse or better than the results you would expect from other similar games.
The one aspect that originally got my interest was that of command control and unit integrity. I do like the fact that the game is based around a 'proper' if somewhat generic unit structure. However, there is no real requirement to maintain unit cohesion although there are obviously game advantages to doing so, and therefore, that works to an extent.
Like JD, I found the contour lines /LOS a bit of a struggle, although to be fair, its often an issue with other games, so I guess its really just a matter of getting use to it.
The thing I did feel is bit odd about the system is that units that are marked with a hit modifier marker, and then subsequently move, carry that marker with them. I'm not saying that this is wrong, but I would have thought that this would incur a penalty of some sort that would reduce the effects of the fire, as in being a moving target. I think this happens with the vehicle rules, but I have not got that far into it.
Its certainly an interesting game, but would I buy it?
Maybe, but only if I could find a decent pre-owned copy of that and the first expansion. I'm not really interested in the EF or Pacific expansion, but would be very tempted by the next one which will feature British & Commonwealth forces - something which, as I may have mentioned before, is sadly lacking in tac games (ASL not withstanding).
