I can live with 256 color bitmaps -- often that's a limitation of driver interface.
I'd love it if they took the time to offer a wider range of variants, all with different weights due to varying armor plating, self sealing tanks, and weapons loadouts:
Ki-61-Ko: 2x 12.7mm, 2x 7mm (think: C.202)
Ki-61-Otsu: 4x 12.7mm
Ki-61-Hei: 2x german 20mm in wings, 12.7mm nose
Ki-61-Tei: What we have in AH now, 2x IJA 20mm in nose, 12.7mm in wings.
I notice the screenshot mis-labeled as Ki-61C. That's not the accurate name. Even using the Western nomenclature which is often easier to understand, it would be the Ki-61-Ic, and that's not the model we have now. If you look at my list above, it corresponds to -Ia through -Id (in order). The -c model had German MG151/20s sticking out the leading edge of the wings and 12.7mm in the nose. You can see the 3D graphics match the -Id variant, so I assume that's just a typo. It gave me a moment's hope that we'd got the earlier, lighter version.
Looking good, though. Looking good.
