User blog comment:AtlasFlame206/Is there gonna be a possible Fairy Tail/Rave Master crossover story arc?/@comment-7418318-20130815133827

I'm not a big fan of cross-overs of different universes. One-shot Omakes and OVAs for fun are okay, but full movies or arcs no thank you.

Also they'd either have to disconnect one group of protagonists from their own story, or introduce their story to the series they get "imported" into. I'm pretty sure I'm not the only one who hates episodes that do nothing except re-telling the story so far. A very regular and annoying occurance in pretty much every Gundam series, except the very short ones (like Unicorn) for example.

An OVA/Omake is done for the fans of both thus no explenation or introduction is necessary, but in a fully integrated arc you can't expect the Fairy Tail-only fans to have the necessary knowledge about RAVE or tell them to read the manga to understand what's going on....
