This might not be what you're looking for, but I really think that you as the game developer should choose the tool. VX Ace is a tool, 2k3 is a tool, Game Maker is a tool, programming languages are tools. They all have different things they are good at and different weaknesses, so most of the decision is influenced by what type of game you want to make and how you want it to play. This is similar to drawing supplies: tablets are tools, pencils are tools, pens are tools, markers are tools.
From my experience all these enterbrain things are pretty much the same in tools and difficultly, except for the built-in scripts editor in Ace, which gives space to some imagination, from editing the menus to changing some in-game mechanics, and some minor stuff.
I learned to use it without touching tutorials, by making a test game and exploring all the features, that's just easier to me.
True! I've talked to a few ynfg devs and since most of them have used 2k3 I figure it may be easier to find help for this specific project. I do like VX Ace, though.>>109
The main concern of mine would be tileset creation. I don't understand the tileset creation process and layout for VX Ace and I've heard 2k3's tilesets are easier to understand. Is this true? I've been looking into it and it seems to be that way.
RPG Maker XP for life! It's not lo-fi like 2k3, and it's mapping system isn't constrained like VX Ace. It's the best of both worlds.
FYI the eventing system is nearly the same, so any tutorials you find about that can carry over. Are you looking for Yume Nikki tutorials only? Because VX Ace is/was way more popular that 2k3 ever was, if only because it never had an official translation until last year.
But VXA's tile stuff should be easy enough to learn if you read tutorials (like http://blog.rpgmakerweb.com/category/tutorials/
) and read the help manual.
