Currently, I'm busy with DF. But I can't figure out what to do now that we've found out that the egg isn't in the black dragon box. But I do have some problems/praises for each game.
DragonFable
Praises
1. There are many more in-depth quests to take part in.
2. It's walk-through.
3. You don't need to fight to train your stats.
4. You don't need to find the untrainer to use it.
Problems
1. Why did they need to use the same characters?
2. You can't get good enough weapons without having a DA.
3. There's only three classes (as far as I know).
4. It takes forever to level up.
5. Where's the shields?
Adventure Quest
Praises
1. I'm more familiar with it.
2. You can get good weapons and pets without being a Guardian.
3. There are many good classes.
4. There are clans.
Problems
1. Activity? Where is it?
2. You need to battle to train your stats.
3. You need to find the untrainer before you can use it.
4. It's not walk-through.
So, all in all, I like them both equally as much.
