Corsairs<==>RoS <==>CR/IMG That is what i call "interaction"... hehehe, seriously though,
*IMG needs BMM to grow (RPwise), for time being IMG balances their politics between Kusari and Bretonia while interacting with Outcasts and CR
*RM is also kinda occupied with RHA and VF and AU, but mostly RHA which also have Corsairs to play with...
*Liberty has ... Xenos, which win in any aspect of the game, and what Liberty misses is LH back in their full glory and LR in greater numbers, Liberty has most factions in territory so i suppose opportunity is greatest there (NY excluded)
*KNF - GC/NovaPG, that is good interaction, but not constant one.. and Kusari in general is ,IMO, most neglected part of space
*BAF pushed new blood in Bretonia's veins , Kudos to you, also NLH, MR and 'sairs who made Bretonia interesting again (4 months ago... Bretonia was almost empty land)
