My choices currently are Cromwell B, Strv 74, SU-100 (with both guns available 122 & 85) and The Japanese Tiger 1

I’m currently thinking about getting these:

O-I (had it before sadly decided to sell it a long time ago – I regret)

M6

T-34-85M (have it but didn’t use it much yet)

KV-2

Any other recommendations, or a comment about my current choices?

Thx in advance ^
