Pokemon is one of the best turn-based RPGs ever made. It's not a coincidence it's such a popular game. There is a lot to learn about the game and it can be very hard to master. There are dual-type Pokemon as well as monotype, either one possessing its own advantages. Monotype Pokemon only have a single type, which means that if they're Water-type, they have a secondary type just as Flying, for example. Dual-type Pokemon can have both types at the same time - this is a double-edged sword, however.
