* Of all the
generations, Generation I introduced the most [[move]]s to the series, with 165.
** Generation I is the only generation in which the total number of moves is greater than the total number of Pokémon.
* As far as release dates go, Generation I is the shortest generation in North America, partly due to the fact that Red and Blue were not released until 1998, while in Japan, they were released in 1996, and their successors, Gold and Silver, were released closer together, in 1999 in Japan and 2000 in North America. As the rest of the world's releases are more similar to the North American releases than the Japanese releases, it is also the shortest generation worldwide<!--but don't take my word for it; do the calculations yourself!-->.
