A few more impressions...
Single-player is challenging, just like the old Bombermans...A little more variety in level design would have been nice, but it's good anyway...The bosses (I've fought two so far) were fun and the means of killing them were different...I expect each boss will have different methods of defeat, which is nice
Multiplayer is obviously the meat of this, and any, Bomberman...I played through a few more modes, such as Skull (played in a graveyard with lots of mystery items (which end up mostly being skull items, yuck), Speedy (everyone starts off really fast, but to make up for it there are a lot of sandals, aka speed-downs), and Voice Bomb (you speak to lay your bombs, which is a lot of fun actually)...The bots are obviously cheap, which isn't surprising, but it's still fun to find out ways to get around their "all-knowing" behavior...Can't wait to play with actual humans, though...
Is it worth the purchase? If you are a Bomberman fan, definitely! If you haven't played a Bomberman game before and are thinking about making this your first, do...It's great, and it's 8-player 1-cart multiplayer for crying out loud!
