Bomberman Generation (Game Arts/Hudson, 2002)
A Bomberman adventure game that seems to also have some very light puzzle elements. Waiting for bombs to go off/grow while you're holding them is tedious and it was already repetitive within the first few minutes.
Bomberman Jetters (Hudson/Majesco, 2002)
Basically the same game, which is probably not surprising given that the Japanese releases were only six months apart. It adds annoying voice acting and gives Bomberman creepy long legs.
Bomberman Land 2 (Racjin/Hudson, 2003)
A Japan-exclusive minigame collection where you're trying to be the first to collect 120 puzzle piece rewards and be crowned Piece King. It has cute GBA-style graphics, but the minigames I saw weren't anything special and it's kind of long winded.
Bratz: Forever Diamondz (Blitz Games/THQ, 2006)
I've always found Bratz to be incredibly visually uncomfortable, and this art style somehow makes them even worse to look at. At least from behind she just looks like some kind of living hairball, which would absolutely be an improvement on the giant-headed monstrosity Bratz really are from the front.
Bratz: Rock Angelz (Blitz Games/THQ, 2005)
This is the same game with the stores rearranged slightly and a different main character, but with almost all the same assets and even some repeated dialogue. Apparently being into rock means you have to be super depressed about everything. You'd probably think these released alongside each other, but no, this came out a year earlier and then apparently nobody worked on the other game for more than about a week.
Buffy the Vampire Slayer: Chaos Bleeds (Eurocom/Vivendi, 2003)
A brawler based on Buffy. Combat is pretty simplistic, but it works decently well. I can see it being worthwhile for someone who is/was into the show.
Burnout (Criterion/Acclaim, 2002)
You can see the outlines of what this series would become, but in the first game it's a simple racing game that happens to encourage you to drive dangerously and has crash animations that aren't particularly detailed. It doesn't have many choices for vehicles or tracks.
Burnout 2: Point of Impact (Criterion/Acclaim, 2002)
And this is where it took off and became a much bigger series. The sequel moves the emphasis from racing while happening to also drive dangerously to driving dangerously in order to race faster, and it brings in the replays and focus on crashing that Burnout is famous for. A list game for sure.
Bust-a-Move 3000 (Taito, 2003)
It's Bust-a-Move. This just isn't a game I want to play for very long, so a full length release never had much chance with me. You might have more luck if you're a big fan of the series, but this particular release was also panned on all systems for being too basic. The GCN version got doubly negative coverage because it's a delayed and renamed port of a PS2 game that ended up being mostly the same game anyway.
Butt-Ugly Martians: Zoom or Doom (Runecraft/Vivendi, 2002)
This was PAL-exclusive on GCN, probably because the US PS2 version came out just after the PAL GCN port and was received terribly, so there wasn't much reason to take the time to bring it over on another system. It's an unfunny F-Zero/Wipeout knockoff that feels slow and has barely noticeable powerups.
