The only thing that really bugs me here is what they did to the chip system. If you want to get them you have to both use a guide and grind, which is so weird for a Mega Man game, for one of the sub-tanks there's something like that too. I also like the elf system of Zero 3 better, but here is good too, level design is very good and the bosses are by far the best from the series, and it also has the best final boss song from the franchise
