I started the Fan Site back in 1999, and even got Tecmo's blessing in writing, and I've also got IMDB/game credits in two of the games in the franchise from before the KoeiTecmo merger . It's been a hobby/obsession for over 2 decades that all started... mostly because My wife had beat the 1st game before me in '97, just waiting for me to get home from work to show me.
The Monster Rancher community is much smaller and overshadowed by other communities by comparison. MR's genre is pretty niche and hard to spread the word because of it, so I try :)
