Gameplay > Graphics.
In bomberman you go around either one or two screens placing bombs, these destroy blocks and clear your way to your enemies, which are defeated with bombs as well. The areas cmmonly have blocks in the middle of each small group of free squares, which gives a place to hide from bombs blasts.
Through the game you'll find loads of power ups which can: Increase your speed, increase the length of your bomb's flame, allow you to lay more bombs at a time, get full-strengh bombs, detonators, bouncy bombs, kick bombs throw bombs and more. This adds a decent level of variety to the game.
The game has tow modes mutli-player and single-player. In single player you go through various stages tryign to defeat the enemies there, each eneie has it's own AI or pattern which can be learnt easily and exploited. You progress though the series of stages and then fight the boss using whatever items you managed to acquire throug previous stages, you loose them if you've got them equipped and die, it does however, allow you to save them rather then equiping them.
In multi-player you select which sort of game to play varying from normal stages, block-free stages, crown stages, cature the block and more. You cna wirelessly and with only one game play with up to seven friends. If you loose in a mutli-player game you'll be able to use a touch-screen cannon to try and redeem your demise and come abck to play again, this feature cna be enabled or disabled when you're choosng what gameto play and the rules for them.
The game has the graphics of the modern Pokemon games and uses them well. The game hasn't got so much freedom as some would like but it is certainly an entertaining game and can keep you playign for hours.
