So roughly, here's what's lurking in boxes... scary...
6mm Ancients - I have lead for 4 armies
6mm ECW Scots - a good start, but plenty to do.
6mm WSS - British half done
6mm Napoleonic Peninsular British - a good start, about 20% finished to a standard I am happy with
6mm FPW - low on the pecking order
6mm BKCII - lots done, but still have enough to do early war French, more Early War Germans, Normandy/Italy Germans, plus huge Commonwealth (Normandy) forces to do.
6mm CWC - not much unpainted, but the SADF and Vietcong to finish. Plenty of spare stuff for smaller forces too. I am not sure whether I shouldn't split out the main Arab style forces and get some done up as genuine Warpac, 1960s/70s British to do (Centurions and Chieftains.. yummy), finish off the Desert Storm Brits too.
6mm FWC - 3 more armies - including the very beautiful Dark Realm stuff, plus bits and pieces for the SAC
15mm Ancients - I must have the lead for 20 - 30 DBA armies, and at least 5 or 6 DBMM armies, Egyptians, Thebans, Any number of Arab types, Sui Chinese, Italian Condotta, WotR and way more.
15mm ECW/TYW - hundreds of figures, but still bare lead
15mm WW1 - have enough for a decent sized British HiTT Force plus aircraft
15mm Moderns - heaps plus vehicles for Iraq/Afghanistan, plus stuff suitable for AK47, somehow ended up with 4-5 Abrams as well...
15mm Sci-Fi - two decent sized forces for Tomorrow's War plus vehicles etc.
28mm Ancients - just Sasanians & enough GW Empire & Bretonnians to do medievals as well....
28mm SAGA stuff - enough for a couple of warbands, plastic and metal Vikings mainly
Then there is all the other stuff...
Full Thrust - 3 fleets to finish, extended SAC, additional Japanese, and finally finish off the UNSC.
DBSA - I have almost another 20 1/3000 WTJ ships to finish, plus 5 Houstons ships for Ironclads
Napoleonic Naval - about 20 Langtons 1/1200 French to finish.
Asterix the Gaul figures.. I have been buying steadily on eBay, and have almost the full set to paint.
