- OS: Japanese version of Windows XP/Vista/7 (both 32- and 64-bit)
- CPU: Pentium 4 2.0 GHz processor
- RAM: At least 512Mb
- Display: 1024x768 or greater
- HDD Space: Minimum 400Mb
- DirectX: Yes, DirectX compatibility is a prerequisite
- Internet: Internet connection for authentication
These are the minimum, anticipated stablest specs required, though the website doesn't guarantee RMVX Ace will work efficiently, depending on how the Maker is used.
RPG Maker VX Ace adds following features:
- Updated RGSS (Ruby Game Scripting System) to version 3;
- Return of multiple tile sets support (omitted in RMVX), which includes "passability" and "bush";
- Modifiable skill and item attack damage formulae, set in the Database;
- A character generator (based on the Chibi characters, which I personally do not like one bit!), as well as a corresponding character portrait editor;
- Additional effects, such as "provocation" and "cover";
- Characters will follow you around "caterpillar" style, i.e. walking in formation on the map;
- The addition of a fifth party member;
- Increased eventing functionality;
- Adjustable damage formulae;
- Customizable combat scene background, comprising 2 mergable background images;
- Introduction of a new regular battle parameter, "TP", which accumulates during combat and when it reaches its maximum allows a new, devastating attack, usually known as "Overdrives", "Limit Breaks" or "Finishers";
- The return of movies in the event scripting, this time in OGG Theora format (I don't know anything about that).
