I have never played any bomberman game, so I took a chance with bomberman 93'. It's definately worth checking out.
In single player you play as Bomberman while setting bombs to destroy all the enemies in the level under a time limit, while trying to find the level's hidden power-up and exit. At the first couple of levels, enemies are stupid, slow, and can be killed with one blast from a bomb. Later, however, the enemies get smarter and faster; sometimes having special abilities such as being able to go through blocks or to shoot projectiles. Sometimes they take more than one hit to kill. Every now and then you fight a boss at the end of each world. You can have 3 save files, otherwise you'll need a password.
Overall, single player is pretty good, not too easy but not too hard.
Multiplayer:
This is the game's highlight. Bomberman 93' has 5 player multiplayer. You need 4 wiimotes and one gamecube controller for 5 player. (if you want to play by yourself, this game has computers) There are tons of power-ups to ensure chaos. Some levels have things such as conveyor belts, no-bomb tiles, and warp holes which allow a really tricky battle where planning ahead is crucial.
If you're thinking of a game to buy from the shop channel, I would reccommend Bomberman 93'. You won't regret it.
