Pokemon Stranded departs from traditional Pokemon games in a number of ways. To begin with, there are no Gyms or traditional Pokemon Trainers, no badges, no Pokemon Centers or Marts, and so forth. In addition, the game’s main story will be relatively short and straightforward, but there will be thousands of side stories to follow along the way. The majority of game updates will focus on adding new side quests.

Pokémon Blaze Black 2 & Pokémon Volt White 2 are essentially the sequels to the Black & White hacks known as Blaze Black and Volt White. The main feature is that all 649 Pokémon are available for capture somewhere in the game, and the trainers have all had their rosters changed in order to maintain a much harder challenge than the original game, as well as having an increased variety of opponents to fight. There's also a large amount of alternative features these hacks offer, which range from differences to the Pokémon themselves to the presence of a couple new TMs. Additionally, the two versions only differ in terms of their aesthetic differences, such as the appearance of Opelucid City, the title screen, etcetera. So basically, just pick whichever colour takes your fancy!
