Naaah, it shouldn't be

RPGmaker is good! If its used for what it was ment for the first place. Its not a visual novel engine. Ren'Py was made for that explicitly. IF someone wants to tell a visual novel through rpgmaker, make the whole walking part minor. You don't have to add 10 maps and force the player to travel those all the time for the sole purpose to get from point A to point B. Rpgmaker isn't made for that. Its made for questing, to talk with those random little npc's to have little dialogues with them and most importantly.. for random encounters. Its a classic rpg engine, Final Fantasy in mind first and foremost.
