AH doesn't "need" a Brewster per se, but there are some who would like to see it added. I'd rather see a Finnish bird added than more LW/RAF/US birds.
We have four FW190 models, five 190 models, yet we hear clamoring for more more more of them. In the same breath, the same folks say the US and Brits have enough planes......lol.
Would be nice to see some of these folks get off the LW bandwagon and encourage HTC to add more IJA/IJN/VVS aircraft, ya know?
