Well first of all, i'll have to say this again. Bomber man is a game out of production in 10 years, and is also is made/publish by KONAMI. This game specifcally should have been nerfed to indie title status and been less than $20. I don't care if it did have a story mode, and voice acting and probably lots of money for budget, is not worth the same price as common retail games. It shouldn't have even been retail, it should been digital only.
Now i won't bash the game cause is bomberman, i remember, how the game works and how fun it is to play with people. But that is my point. A game YOU PLAY WITH PEOPLE. That is where the fun of the game is, most of the reason why people play it. Sure it has a story mode, over 50 stages, then what? After you are done, multiplayer. Unless you have friends to play with locally or online (Not sure if it support online or not) Then you have a game that just as worth playing call of duty, titan fall (with no campaign mode) or any other game that gets is value by playing against someone else other than making a game with enough content to do alone.
Single player content is just always important than multiplayer. Go check wikipedia.org for is information, even there it says, it has mixed reviews and mediocre stuff about it. Trust me when i say this, If you wanna play a GOOD bomberman game, try Bomberman 2 on NDS, to me is the best bomberman to date, it has a great single player mode, and multiplayer mode, including download play. Just look at it.
