I gave this opinion on the WAB forum and thought I would share it on my blog.
I've been reading HC and so far my opinion is.......I'm impressed! I like the mechanics of the game, orders and blunders mechanism, and the ability to design battles and armies as you see them reflected in history. It does require an emphasis on game building which I find very nice.
While I do enjoy points driven gaming(WAB, Impetus etc.), I equally enjoy the freedom to design armies and battles free from points limitations to better reflect a more historical gaming experience(simulation gaming in other words HC ,F&F BG etc.)where battles were seldom fair and therefore requires one to design scenario goals and objectives to level the field rather then abstract points.
An interesting point about HC is it's geared towards multiple players that can be played with just 2 players while most other systems are designed for 2 players that can be played with multiples. This should not be over looked as large battles will run very smoothly with HC as that's it's comfort zone and requires very little adjustment.
This type of gaming is ideal for club/group gaming or demo games. If your a little weary of the tournaments and want to try a change of pace then Hail Caesar is something to try.
Generally it's designed for large games due to the high figure count, but will still work with moderate sized armies.
If your a small sized collector say in 10mm or 15mm this system will actually give you the rule set to take advantage of large collections that you otherwise couldn't fully use them all and for the 28mm gamer a chance to really pool a lot of miniatures together with friends and not worry if you have too much as the rules allow for adjustments in scenario's and unit capabilities to help off set any large disadvantage to one side or the other.
If your looking for absolute fair then this isn't for you, but if your looking to just play your miniatures with some freedom and let history design your armies then I really recommend HC.
Another point is I really like Impetus and HC easily accommodates the basing which is nice. I'm a huge fan of Impetus basing, but was always concerned it made playing other systems difficult, but not so with HC thus any army I base for Impetus I can use with HC as well which avoids any army becoming to narrow in possibilities.
Also, I heard Rick has published some lists in the yahoo group. I personally hope that's as far as it goes and no more lists are added or ever published. Lists will eventually replace players freedom and in the case of HC I think that's not a good thing. Many games have lists and that's good, but I also like games without them and so I hope HC avoids this.
