I think these are not on the list, so at least some can be added probably:
slave's sword Basic typical rpgmaker game, decent story maybe too simple
slave's sword 2 Still not played, sequel to the previous one
Imperial knights Sequel to the previous 2 titles, this is a masterpiece with 3 playable routes, found some little bug in route A ending, maybe they should have worked more on balancing but i still have not completed all of it.
erodungeons This probably is not present for a reason, but i propose this title as it has many features of the other games in the list: turn based combat, in fight-strip and different types of in-fight-restrictions. An extremely well balanced game, not simple and not impossible.
