Currently, there are nine Generations in the series, spanning from the Japanese releases of in 1996 to in 2022. These generations create a timeline that is seemingly broken down into sections based on when each new region was released. However, the timeline is actually based more on which year each game was released, regardless of the region the game takes place in, and this can be confusing from an initial standpoint. A way to help break down where each game falls on the timeline, including each of the remakes, is to look at the year the game came out.
Using consoles used to be a good way to know where in the timeline games fell, but this method hasn't been so reliable since the Nintendo DS, which started hosting multiple Generations. Generations have since had an overlap on the 3DS, as well as on the Nintendo Switch, making it much harder to distinguish timelines based on the platform the games can be played on. Many older games have become dated and no longer available on modern platforms, forcing players to find outdated systems and vintage cartridges to play them. Because of this, many of the older games are being remade for current consoles.
Below is the currently registered timeline for the core games according to the fandom wiki Bulbapedia. The timeline is arranged to show the Generation, the consoles the games were released on, and the year the titles hit the market. This will help players visualize where all the core series games fall in the timeline. This doesn't include spin-off titles like or, which aren't part of the game's main series.
