Hopefully they will make another final fantasy X-2. I think focusing on rikku might not be the best idea. I think it should pick up where it left off....looking for Tidus. There should be something that happens to bring back all the summons or something she has to do to bring him back in particular. It should also get back to having different characters other than the three main characters from x-2. thats just my thoughts on it lol
oh and if anyone does decide to do something in rpg maker I am pretty good with a pencil and sketching is something I could easily do, not to mention animating sprites and the like...I miss the old editing programs though. I used use ACE for sprite design but I can't even find it anymore
