Hi, thank you for your reply.
Yes, I understand that a lot of the system in place are basic RPG system and will be refined as time goes. I hope I didn't come across as intrusive to the development of the game. I would love to have back-and-forth discussion on this if you don't mind. Just putting out thoughts as a consumer, so please take my comment with a grain of salt.
But coming from a perspective of someone who like and used to play a lot of JRPG (same as you through the PS1 era), I expect to see a dramatic story, cool characters, or environment at the beginning of the game to get invested in. If you guys are indeed planning to do a full JRPG for the project, I think making a well-crafted story, with engaging plot, intriguing characters, or cool environment first (just for the beginning part) would be the utmost priority for what you want to achieve? Implementing the battle, inventory or tutorial system seems to be secondary for the type of game you're aiming.
