Thanks for the 28mm IABSM resources, Olivier, these look very handy indeed. Interesting that one of your games lasted 5.5 hours - I have found the scenarios in the new rulebook last over 2.5 hours, though I'm a new player so maybe things will speed up!
In response to the question about comparing the old and new IABSM (v2 and v3), the core system is the same but the new rulebook is 100% better in terms of accessibility. I bought the v2 rules and never got round to playing it; the v3 rules have inspired me to collect an army and I've now managed 4 games already. Being able to buy the cards also makes life quicker.
