They nail B&P precisely, but they're long in the teeth. Panzer Corps is probably the way to go, these days.
Steel Panthers, when it first came out, was probably Grigsby's most B&P design, ever. Its latest necrotic incarnations, fueled by the nightmares of billions of rivet-counters, aren't.
I wish there was just a fixed-up version of SP1-- the basic game, bugs fixed, working in a modern OS, nothing else.
