I've had a read through of the rules, and they are very like Lion Rampant, much more so than TMWWBK.
As to a comparison to Pike & Shotte, well apart from being in the same era there is nothing much in common. PL is a skirmish set with perhaps 4 units per side. PS is large battle with perhaps 16+ units per side. Both have command roll mechanisms. But the look and feel of combat is very different. If your group wanted the size of battles of P&S then PL probably won't work instead.
