The best fangame ever, and no one can deny it:
I Wanna Be The Boshy
Agree. In my opinion Boshy is the best fangame I've played because it looks awesome and I'm quite sure it has a lot of work on it. And without Boshy many fangames probably wouldn't exist (all the fangames that feature Solgryn as a boss), as I'm quite sure Boshy impulsed the authors to make them. Maybe I feature Solgryn in my fangame as well! 
Two terrible reasons for liking a video game. Treating Boshy like the de facto king of fangames because it looks good is like saying the Concorde is the best aircraft ever because it's got a really cool pointy nose. Also that's completely false: those fangames would likely still exist, just without Solgryn as a boss in them.
That wasn't what I meant. The fact that it looks awesome just makes it look like it has a lot of work on it and makes me like it more. Of course its not the reason to like it! I already said I was a
Nintendo fan and we all now Nintendo does not have the best graphics.
And the fact that the authors of the other fangames feature Solgryn means they played and liked Boshy, and problably its the game that impused them to make their own fangame. In my case IWBTB and IWKTG are the games that impulsed me to make my own fangame.
Boshy is my favorite fangame, maybe it's not the best, but I still think its a very cool game. When I see a fangame that is better than Boshy
(IN MY OPINION), I'll tell you.
