Following my recent DBMM AAR postings, with clear head and happy heart I can make the following announcement (to myself) ...
DBMM (version 2) is now my official poison of choice. (With the caveat that the figures based for these rules can still be used "with the aid of sabots" for Impetus)
So DBM is dead for me but in all honesty has been for some time (the phrase cutting my losses seems apt here). It was only ever a competition orientated system (IMHO) and evolved slowly into a Byzantine geometry form of participation art rather than a vehicle for historical gaming.
DBA was and still is a seductive alternative (or rather was) but the pragmatics of both learning two 'similar but different' rule systems and remembering the rule differences when playing is just self-defeating. It also has the famous "rule of twelve" that artificially gives battles of "even sized" armies. The smaller DBMM 100, DBMM 200 allows an army to slowly grow in size :)
Please note the above is just a personal choice ;)
