Gonna give in my thoughts, too.
Reborn has always been a memorable game to me. It did what no other fangame did at the time (and many still don't), and that is having a story worth a damn. The fun cast combined with unexpected plots + field effects makes for such a great experience compared to the things we've already seen done in pokémon games. Reborn uses all the potential things a fangame can do and more. It's simply more than just a pokémon game now, and it spawned a community and opened up a wave of a new era of fangame potential.
Can't wait for e19!
