Do not even consider renting this game!!!
The controls are by far the worst i have found on a wii game.The maximum is a 4hit combo and movement is plain stupidness,trying to get near your opponent and still not being able to reach him with your weapon.
Weapons are another big chapter.When i started story mode and i was told to choose a weapon i was happy because i thought there would be a variety of weapons for each character. HUGE mistake.You take the weapon from the opponent you win and thats all,meaning that you are not going to see any new weapons for the characters.Of course you can take all the enchantments of your opponents but there is no big difference between them.
Each character has 3 different magic abilities which you can spam in order to win,but this is not necessary once you can win by just button smashing if you are using classic controller, otherwise with a wii mote you are going to lose your hand.
So,if sega decides to lower the price to 5-7$ i think then it would be more appealing to the crowd...
