the shop was just for public use, I just used that from googling for merchant characters, lol, I didn know it was from mabinogi though, never played it.
I'm still trying to find a CG to use for my own game, that cg would clash with my own :\
and they really arn't that big... if you compare to her cg, as well as if you looked at the sprite on 1x view in a rmxp map, it's fine.
anyways, the game is using a tactical battle system, the battles will probably be from 10-15/20mins like you said, theres 3 missions (out of 5 choosable missions with a mission system) which will be the main focus of each day, and 3 story fights, which will happen at points int eh story.
the entire story is worked out, and it's great, I'm sure you'll love it, but yeah.
there'll be 1.5 hours or so of battles, and the rest is all story and prepping for battles like any other tactical game.
for the battles, you have the main character, Avion, and up to 3 mercenaries.
for the mercenaries, theres a very simple mercenary system with 3 classes, Knight, Warlock, and Priest, you can customize they're gender, weapon, and affinity skills.
depending on the battle, you'll also have story characters with you as well, the 3 possibilities are of Fukai, Miho, and Sakuran, the 3 girls.
the last two cast members are just the bad guy, and Miho's dead father.
