NosTale vs Pokemon Planet
NosTale
NosTale is an anime-inspired MMORPG filled with adorable, chibi-like characters set a vibrant, colorful world. Specialize your adventurer into either a Swordsman, Archer or Mage and set off on an amazing journey to catch as many pets as you can for your collection, or if you're a tad bit more picky, to catch only the strongest pets so you can win all your battles. Sometimes, you will also get an NPC as a companion on your travels. Players are given plenty of methods to improve their own characters along with that of their pets and companions. In addition to the usual PvP and PvE content, the game even has special events that will teleport you to a limited-time mini-dungeon where you'll need to fight various creatures and enemies alone or with some friends.NosTale is actually quite similar to other cute-looking, pet-catching/collecting MMORPGs where pets play an important role in the games' combat system, much like Digimon Master Online or any Pokemon game. So, if you enjoy this sort of games, you might want to check out NosTale!
Pokemon Planet
Pokemon Planet is a Pokemon-themed, MMO adventure-RPG where you'll not only get to strive to "become the very best like no one ever was"; you'll also be able to assemble a team of Pokemon from various generations/regions (except the ones from Alola). It even features graphics that will definitely twinge that sense of nostalgia in your heart, especially for those who have loved Pokemon ever since their childhood days.The game plays out pretty much like the usual handheld Pokemon games of old, except that this time around, the game is an MMO and hence, you can actually interact with other players in the game. This does make trading Pokemon or dueling a lot easier. However, since the game is not Nintendo-affiliated, the developers are restricted from using certain assets of the franchise, which apparently includes animation and sound effects, but oddly enough, that exclude all the Pokemon designs and every other game element in the game like Gyms and Pokemon Centers.
Although Pokemon Planet is not a Nintendo-created game, it is the sort of Pokemon game that fans of the franchise have always dreamed of. It has the entire package, from the nostalgic graphics to all the Pokemon you can possibly catch (and then to duel other players with). Personally, I believe Pokemon has always been a game that's just primed for an MMO game, and Pokemon Planet simply one-up Nintendo by turning that into a reality (first).
