Of course, I get you, and yes, a preview really helps a lot. I’ve been working with RPG Maker for years myself (over 15 years of experience), so at this point memorizing coordinates and understanding how they work has basically become second nature to me, haha.
Still, I know there are plugins that make this task much easier. For example, some let you skip having to enter coordinates manually and instead just “walk to X map coordinate or X event” directly through a plugin command. I suppose MV must have something like that.
And yes, that’s true. MV has tons of plugins. The case with MZ is a bit more complicated, because it’s by no means a bad engine; in fact, I personally think it’s the best version of RPG Maker ever made. But many users don’t feel its price is justified compared to its predecessor (of course, that’s just personal opinion). Nowadays, there are already plenty of plugins for RPG Maker MZ, and the cases where MV has something that MZ still doesn’t are very few and quite specific.
But well, beyond whichever version one uses, what really matters is being satisfied with the end result. :)
