SmashWiki, while covering a large spectrum of topics, doesn't (and shouldn't) cover in-series content that doesn't relate to Smash. Hence why, as I recently pointed out,
- Mr. Resetti has a link to ACWiki,
- Quick Attack to Bulbapedia,
- Diddy Kong to DKWiki,
- Isaac to Golden Sun Universe,
- Smart Bomb to LylatWiki,
- Petey Piranha to MarioWiki,
- Meta Ridley to Metroid Wiki,
- Wii to N-Wiki,
- Distant Planet to Pikipedia,
- Infantry & Tanks to Wars Wiki,
- PK Starstorm to WikiBound,
- Star Rod to WiKirby and
- Bunny Hood to ZeldaWiki...
Such links allow readers to learn more content about game elements that appear in Smash as they appeared in their source series. However, as I'm sure you're aware, some of the content in Brawl comes from non-Nintendo games, and therefore their in-series history is not covered by NIWA wikis.
Therefore, I thought I should ask: if SmashWiki were to affiliate with independent Sonic and Metal Gear wikis for the purposes of interwiki linking, what would be our best available options?
