The penultimate post.
Warrior Blade: Rastan vs. Barbarian (Saffire/Taito, 2003)
A 3D arena fighter with destructible environments and transitions between different areas of the stage when fighters get knocked off of platforms. It was a Japanese exclusive on GCN and a PAL exclusive on Xbox, but the PS2 version came out everywhere to mixed reviews. Despite that, I enjoyed the arcade mode and I'm putting it on the list for a longer look. Oddly, despite the name being "Rastan vs.", Keela here is first on the character select and appears to be the main character.
Wave Race: Blue Storm (Nintendo, 2001)
The sequel to the N64's Wave Race, and the last game in a series that Nintendo promptly forgot about. You'd probably assume that means it was a critical or commercial failure, but it reviewed well and was apparently the #3 best-selling GCN launch title in Japan, which is no small feat when the competition was Luigi's Mansion and Rogue Squadron. Another list entry.
Whirl Tour (Papaya Studio/Crave Entertainment, 2002)
Tony Hawk but on a scooter. I like the cel-shaded look and the soundtrack seems promising, but I'm not at all equipped to give a meaningful criticism of this genre and it seems to have been generally considered forgettable. I have no idea why there's debug text in the top left and bottom right, but that probably wasn't there in 2002. Papaya Studio only ever made licensed games after this and shut down around 2009.
Winnie the Pooh's Rumbly Tumbly Adventure (Phoenix Studio/Ubisoft, 2005)
An adventure game starring Winnie the Pooh that also has a bunch of Mario Party-esque minigames. This one has mutant velociraptors chasing Pooh for some reason. That's not nearly as baffling as Sony's decision to release it as a PS2 classic on PSN in 2013, though. What was it about this generic licensed title that doesn't seem to have sold particularly well and certainly didn't review well that made it a classic? A good deal with Ubisoft, probably.
World Series of Poker (Left Field Productions/Activision, 2005)
A poker game. You play poker. There are lots of other ways to play poker, so I have no idea why you'd want to do it here. You'd have to sit through some of the longest loading screens ever seen on the GCN if you did, though.
World Soccer Winning Eleven 6 Final Evolution (Konami, 2003)
A PES spinoff that only came out in Japan on GCN. I wish the camera was a little more zoomed out, but otherwise it plays well and looks pretty good for 2003. You also get loads and loads of options for teams and competitions, so chances are you'd be able to find quite a few different fun setups.
Worms 3D (Team17/Acclaim, 2003)
It's Worms, but 3D. There are approximately thirty two billion different games in this series, so I doubt there's much reason to play this particular version of worm-based artillery over others. It seems to have sold well despite slightly better than mediocre reviews.
Worms Blast (Team17/Ubisoft, 2002)
It's Worms again. There's a puzzle mode that isn't very fun. The music and graphics are kind of nice, I guess.
