Dungeon Hunter 3 - (by Gameloft) - Universal App

[Mr. Grizzly]

This is the only Dungeon Hunter I have played yet - and I truly like the dual stick shooter arena gameplay - don't like the quirks of the free aspects of the game (have to wait for keys and to upgrade items). The graphics are great too.

In comparison to ths one, what are 1 and 2 like? Which one is better between 1 and 2? Do the first two have the same kind of fighing, upgrading system (without the waiting), any replayability of dungeons?
