Given the popularity of 'Battle Cry' in the short space that it has been live on GTO, I see potential for other fast play hex based war games.
'Hold the Line' from Worthington Games http://www.worthingtongames.com/
is very similar in scope to 'Battle Cry', possibly one step up the complexity ladder as it includes slightly more unit types. I also think it will appeal to those who do not like the Card based Flank centric, play of the latter but still enjoy the horse and musket period of conflict.
Covering both the AWI and the French & Indian wars, and the ability to play the scenarios from it's predecessor "Clash for a Continent" it offers 32 scenarios, out of the box as it were, and an additional 2 scenarios available for download on the web site, as are the rules.
With 'Battle Cry' under the programmers belt this game will give great 'bang for the buck' or at least reduce the development curve, as the game board and terrain tiles are the same, tactics are similar and no cards are involved.
If you have not tried it, take a look. As a die Hard Command and Colors fan I feel almost guilty to admit that I prefer the 'Hold the Line" game mechanics. To the point that I have even attempted to use the rules with 'Battle Cry' scenarios and 10mm figures.
Food for thought for Jay and co, and a heads up for those who discovered 'Battle Cry' via GTO and are considering getting a good war game to play in the real world too.
