"PSA: What to expect as additional generations get added into the game, from a longtime main series player. [Discussion]"

#PokemonGO: Well, I've been playing the main series games for some 18 years, and I know quite well how the franchise has been evolving in that regard, so, let me put you up to date in terms of what to expect from the future:-Gen III: This generation introduced 135 new species, of which 2 are babies of gen II lines (Marill and Wobbuffet), and 10 are legendaries. In this gen, 2 important features made their debut in the main series: Passive abilites and double battles. Double battles meant there are plenty of "paired" species in this gen, unevolving version exclusives introduced mostly to showcase them, and this gen remains to this day as the one with the most unevolving 'mons. As for abilities, they are quite important for some Pokemon, and if I were to guess, they will probably be implemented in GO. Otherwise Slaking will dominate the game. In addition, this gen has some downright weird evolution conditions, keep an eye on Nincada, Wurmple and Feebas. Oh, and we get two pseudo-legendaries (Dragonite equivalents) this gen, and Dragon types become quite a bit more common, thanks to Swablu and Trapinch.-Gen IV: Introduces 107 species, but, of those, 29 are related to old Pokemon, and 14 are legendaries. To note, Aipom, Misdreavus, Murkrow, Sneasel, Magneton, Lickitung, Rhydon (!), Tangela (!), Electabuzz, Magmar, Togetic (save your Togepi candy until then!), Yanma, Gligar, Piloswine and Porygon2 get evolutions, while Sudowoodo, Mr. Mime, Chansey, Snorlax and Mantine get babies, and Eevee gets Grass and Ice evolutions. There is some expansion on gen III families, and gender-based evolutions are introduced.-Gen V: 156 new species, 13 legendaries, NO relatives to older families. Most of the stuff introduced here parallels gen I species, as this gen started up as a "fresh start". Has many 3-stage families, as well as many candidates for 10 km eggs.-Gen VI: Introduces just 72 species (6 legendaries), and only one of them is related to older families (a Fairy-type Eeveelution). The main featured to be added is Mega Evolution, which is basically a battle-only evolution for already fully evolved Pokemon, and I have no ideas about how it may be implemented in GO, but will probably end up making it.-Gen VII: The current one, introducing 81 species, and doing odd stuff with legendaries (officially there are 11 legendaries, but there are an additional 9 legendary-esque species, AND among those 20, there are 2 evolution families: a 2-stage one, and a 3-stage, branched final form one). This generation introduced Z-moves (once per battle nukes, pretty much), and regional variants of older Pokemon, which are, well, different versions of already existing species (for example, standard Geodude is Rock/Ground, while Alola Geodude is Rock/Electric). No new species related to older ones, however.Also, seeing Legendaries are about to hit, we'd better keep in mind the three categories they fall into in the games, because the incoming gens will increase the number of them a hefty load:-Regular legendaries: They are pretty much hard to get Pokemon with stats in Dragonite's ballpark (hence why Dragonite and Tyranitar are known as pseudo-legendaries). The games usually have no limitations whatsoever about their usage. Articuno, Zapdos, Moltres, Raikou, Entei and Suicune fall in this cathegory.-Special legendaries: The strongest species in the games, usually only found in the climax of the game or the postgame, they have stats quite beyond anything else, but the games usually limit their usage (no Battle Tower, no Poke Cup in the Stadium games). Mewtwo, Lugia and Ho-Oh fall in this cathegory.-Mythical Pokemon: The rarest Pokemon, they usually AREN'T found in the games and are only obtainable via official events. They tend to have stats on par with the regular legendaries (in fact, the original mythical, Mew, had stats on par with Dragonite and both were second only to Mewtwo in the original games), but the single strongest species, Arceus, is also a mythical. Mew and Celebi both fall in this cathegory.And I think that's all so far, feel free to throw any question, and I hope this was of help or, if anything, of interest. via /r/pokemongo http://ift.tt/2risWZd
