When you get past the rediculous learning curve, this game can be quite good.

When I bought this game, at first, I hated it. However; many, many, MANY hours later, I eventually learned how everything works and was able to create something decent. The problem with this game is that the majority of people who are able to understand it are probably old enough and smart enough to use a much more professional game making program, which makes this game pointless.
The Good: This game allows for the creation of virtually any turn-based RPG you can imagine. It grants you the freedom to make the items, monsters, dungeons, characters, etc. The game gives you so many options that the possibilities you can create are endless.
The Bad: Aside from the learning curve, not too much else, but there are some bad things. Making monster fights are almost impossible. To make any monsters where the fights weren't rediculously one-sided, it requires countless test fights. There's a limited selection of monster graphics to use as well. Eventually, the enemies get repetetive in your game.

Also... I think it's worth mentioning. Once you get into the game, a glitch in it eventually occurs. About 2 characters, 3 towns, 1 dungeon, 3 bosses, and about 78 hours worth of work later; your game is randomly deleted. It happened to me and I never played the game again. I ruined it for me.
