Fun the first time, but odds are you wont play it agains afterwards.
Main reason for that feeling is that you cant pick the heroes that you want. Each level you play has a preselected pair of heroes for you that you have to play as. For example the first level is Batman and Superman, but that level aint that long.
And the thing is that during that one level you level up those characters, but when you go to a new level you have a new pair of heroes. So the difficulty of the game increases but if youre given a new pair of heroes with level 1 experience, then the it becomes a challenge.
And there is only 2 levels in the middle of the game where you get to pick your players, but its best that you only pick players that you have a hunch will need later on so that you dont level up characters your not going to use.
There are unlockable characters, like aquaman, huntress, green arrow etc, but you can only use them in those two levels. And its not like you can pick your level, if you beat the game, u just have to play thru the entire game again to get to those 2 levels.
Then there are the unlockable costumes. Say your playing in a level with batman and superman and decide to change there costume, you have to go to the options menu and change it, then once youve changed it, you have to wait to enter a new area before the change in costume to take effect which really kills the whole idea of being able to change costumes.
Its fun the first time, if your a fan, but if you dont buy it youre not missing out on much. Just wait for a real video game developer to come along and make a good justice league game.
Oh yeah before i forget, the voices of the characters arent that good.
