Ok, I'm slightly confused by the easy army site, is that definitely up to date?
Very rough guess so far (I need to sit down and figure out what I'm allowed with how the army structure works), my Empire is at 2500 before I start doing "allies" (units that I'd count as other forces) heroes or magic items. I do have some unpainted bits to add in too...
I think I can probably get to 3500-4000 with that. Then I have my Bretonnians. So I'm sure I could in theory do some very silly number.
Given that they recommend adding 3 feet of table width for every 1000 points above 2000, that means my Empire need a table 12 feet wide, so we may have to start playing on my lawn.
Or, I just have lots of choice when I come to play 2000 point games.
