Game Boy Wars 3 is Hudson’s heavily overshadowed effort at innovative gameplay for the Nintendo Wars series. To make things vibrant in contrast to Famicom Wars and Game Boy Wars 1/2/Turbo, Hudson provided stronger unit variety and more active mechanics. However, creativity often comes at a price of streamlining, and Game Boy Wars 3 had proven itself no such exception to that rule.
The PALBal hack aims to bring structure to innovation, involving PAL-style balancing that does its best to understand how balance issues happened and work off of that, while providing its own creative touches here and there in an attempt to add depth without interfering with general gameplay. Also helping is that the ideas that already provided vanilla GBW3 with surprising player phase friendliness despite one of its big issues are significantly better emphasized.
GBW3 may be interesting from uniqueness in its own right, but even those who have already played it can expect this to be worth a look.
