Reading this is very inspiring. I'm also into game development and want to create an (online) RPG for "tired veteran MMO players". I belong to the generation of highschoolers that spent their free time playing MMORPGs like Final Fantasy XI, World of Warcraft, and Guild Wars, when they just came out. I had so much free time back then, and the energy to stay up until 3AM on a school night just to get that special item. Fast forward 15 years, I still love the feeling of "progress" in games, but I just don't have to time to spend. The extra time that I do have I try to spend on other things that are important to me. I'd love a game which would give me the feeling of progress (especially the feeling of Final Fantasy XI), but doesn't require me to go back to my highschool past.
Everything was thought out, from the core mechanics of the game to how the player should feel and use their imagination. I honestly think Kazuya Niinou did a great job. Reading this diary really inspired me to continue my game development journey. I can spend time doing what I love, work to achieve my goal, and also improve my programming skill / knowledge.
When I talked to our marketing team, I told them I wanted to emphasize that Etrian is "the renewal of the 3D dungeon RPG." What I mean by that is that I hope the genre will thrive again, not just attract the same Wizardry fans.
I think you achieved your goal, thanks you!
