I guess i don't like this show so much as i used to. I havent watched the last 5 eps and i just dont care enough to watch 'em
You just described any major fandom for any other show or movie in existance. Avatar: The Last Airbender, Star Wars, Star Trek, Sherlock, Lord of the Rings, Harry Potter, Fringe, Teen Titans, etc etc etc. Bronies are in no way unique.
Why is it that MLP is popular among gamers in their mid 20s over other series that seem to fit the bill more, like say, Regular Show or Adventure Time? Those are both (arguably) children's shows that include interesting characters, and loads of references to other media (i.e. video games), which are both things that fans of MLP (including Maxi) cite as some of the main reasons they enjoy the show. So, why has MLP caught on in the online community over other shows?
I've watched and enjoyed a helluva lot more girly anime/shows than MLP (if its good its good, i dont really care so much about who it's "for") so to me that wasn't really a barrier but yeah, it has a lot to do with the fandom of it all (like hilarious youtube poops and parodies) that re-inforces the show I think. Then there's people like Maxi who just genuinely really like the show a lot. Bronies aren't really unique other than the fact that the whole phenomena was just so unlikely which makes the fandom that much more enjoyable, espesially since the show's authors acknowledge Bronies in the show itself (see:
Derpy Hooves) . As for why Gamers specifically enjoy it probably has more to do with where the whole Brony thing came from (4chan) than the show's content imo.
also here's an (overdramatic) know your meme on it
