The RAF Battle of Britain 1940 force mix isn't onerous for a collection. The counter mix is shown below which will provide a break down for the models I MIGHT decide to collect. I have a reasonable inroad into the Luftwaffe Forces from the TD Starter pack (9 Do-17's, 3 He-111, 3 Ju-88, 4 Ju-87, 6 Me-109, 4 Me-110) so don't need much and you only need all these models to account for your forces. Actual raids are a lot less.
The RAF don't need that much either. Spitfire and Hurricane packs will rapidly add aircraft to the table if required.
10 Do-17Z (of which 1 is a replacement Gruppe)
16 Ju-88 (of which 5 are replacement Gruppen)
9 Ju-87 (Zero replacements)
25 Me-109 (of which 1 is a replacement Gruppe)
10 Me-110 (Zero replacements)
- RAF - NOT YET STARTED
25 Hurricanes (of which 6 are replacement squadrons)
5 Blenheims (Zero replacements)
No Idea (but I have an inkling) - I have a copy of "RAF - Battle of Britain 1940" on order. From the reviews on BGG I will either run this as Eagle or the Two Player game. Don't think that playing this just as the RAF is going to convert to a convention format.
From the relatively simple graphics on BGG that I have seen, the table will be really EASY to do which means I might get a custom mat from Eric Hotz made up. Now I have opened the box the map is a bit more complex and will need to think about this. Maybe it is just a step too far for this one but the temptation is SO great.
