Another year, another mainline Pokemon release. Going over 20 years and still strong, Pokemon Ultra Sun and Ultra Moon are the latest entries to the multi-billion dollar franchise coming out just one day shy of a year after Pokemon Sun and Moon. Ultra Sun and Ultra Moon (abbreviated USUM) are the last entries to the 3DS line and possibly the last handheld entries as well (though the latter statement can only be assumed). USUM are enhancements to Sun and Moon, the Generation 7 games that came out last year. USUM, like previous enhancement games such as Crystal, Emerald, and Platinum, add new game modes, tweak existing features, expand on the movepool of existing Pokemon and other various fixes to the games.
