Dungeon Hunter: Alliance originally came to the PlayStation Network in April 2011, where it is still available for $12.99. A few months later, the game was ported to Mac, where it has recently been on sale for $0.99.
Gameloft hasn't stopped there, however, teaming up with regular co-conspirator Ubisoft to release another port for the PlayStation Vita. It is more or less the same game, with one major difference -- it's being sold in stores for $39.99.
There are some schools of thought that say price shouldn't be a factor in a review, but ... come on. This is being released at the same price point -- and thus believes itself to be in the same league -- as games like Marvel vs. Capcom 3 or Lumines. So, we're going to judge it on that exact same level.
