First off let me say that I haven't played this mod yet.
BUT
Let me ALSO say that just by the looks of it I will REALLY enjoy this mod a lot. For your first mod you took on a big project, and from what I've read, done an amazing job, so congradulations to you for having such a succesfull begining! When I read the title I was like "crap..more naruto" but you really surprised me! I can't wait to play.
I do have some questions though.
If you take on this quest, can you still do the main quest? Plus if you have a compainion mod (I have Ruined tails tale) will that interfer with being a ninja?
Also I see a lot of people asking for more combat moves. I thought that I would give you a link to this mod called http://www.gamesas.com/bgsforums/index.php?act=ST&f=25&t=608305. It is still in beta, and im not sure if its compatible with your mod (it should be i hope) but it adds a host of new combat abilitys for all weapons including bows, and seems like it would work well with your mod. Maybe you can get it so it comes with yours in future downloads?
Also, theres the http://www.gamesas.com/bgsforums/index.php?showtopic=697026&hl=deadly+reflexes mod that works well with it so people flip and can bash enemys/make them fall down. Yeah... lol sorry for the edits.
Anyways, the mod just finished downloading so im going to go make a smexy elf ninja. Thanks again for the wonderful mod and you can count on constructive critism and the like from me in the future
