I would like to propose renaming the following tags in the Pokemon series:

• pokemon-rse → pokemon-ruby-sapphire-emerald (29)
• pokemon-frlg → pokemon-fire-red-leaf-green* (27)
• pokemon-dpp → pokemon-diamond-pearl-platinum (29)
• pokemon-hgss → pokemon-heart-gold-soul-silver* (30)
• pokemon-bw → pokemon-black-white (19)
• pokemon-bw2 → pokemon-black-2-white-2 (23)
• pokemon-xy → pokemon-x-y (11)
• pokemon-oras → pokemon-omega-ruby-alpha-sapphire (33)
• pokemon-sm → pokemon-sun-moon (16)

These expanded tags would match the naming used for pokemon-ultra-sun-ultra-moon.

Author's notes:

• The official titles for FireRed/LeafGreen and HeartGold/SoulSilver do not have spaces. However, I believe including a dash works better when converted to a lowercase tag name.
• Arqade currently uses a dual-tag system for Pokémon to distinguish generation-wide and game-specific questions.
  • Example: pokemon-fifth-gen vs pokemon-bw & pokemon-bw2
