Once you learn exactly how everything fits together, it's possible to make great games.
You have tons and tons of sprites for monsters, characters, objects, and environmental set pieces. These range in style from sci-fi to olden fantasy, and can be used for nearly any purpose; their collision data is built in, though, so be careful the player can't walk over a desk.
It's even possible to create your own sprites with the Anime Maker tool, although it's not even worth bothering if you don't have a mouse; there's no support for analog sticks, and the D-pad is not fun to draw with. With the amount of text you have to enter in with the on-screen keyboard, however, it's a shame the game doesn't work with any kind of keyboard.
Overall, if you can find this game, it's worth your money. One precaution: the game does not autosave ANYTHING, so you have to b careful not to overwrite any system or scenario data. Also, it's a shame there's no way to distribute your games aside from copying the data onto multiple memory cards and buying multiple copies of the game.
